a517290ea7 rbd: let parseVolCreateRequest() return a connected rbdVolume
By returning a connected rbdVolume in parseVolCreateRequest(), the
CreateVolume() function can be simplified a little. There is no need to
call the additional Connect() and detect failures with it.

7b2b125b18 rbd: free snapshot resources after allocation
Not all snapshot objects are free'd correctly after they were allocated.
It is possible that some connections to the Ceph cluster were never
closed. This does not need to be a noticeable problem, as connections
are re-used where possible, but it isn't clean either.

991343d9e5 cleanup: do not pass EncodingVersion to GenerateVolID()
The only encoding version that exists is `1`. There is no need to have
multiple constants for that version across different packages. Because
there is only one version, `GenerateVolID()` does not really require it,
and it can use a default version.

If there is a need in the future to support an other encoding version,
this can be revisited with a cleaner solution.

3bf5c0e478 cleanup: simplify rbdGetDeviceList()
The `rbdGetDeviceList()` function uses two very similar types for
converting krbd and NBD device information from JSON. There is no need
to use this distinction, and callers of `rbdGetDeviceList()` should not
need to care about it either.

By introducing a `deviceInfo` interface with Get-functions, the
`rbdGetDeviceList()` function becomes a little simpler, with a clearly
defined API for the returned list.

f60a358007 rbd: do not try to run resizefs on an encrypted BlockMode volume
When a volume has AccessType=Block and is encrypted with LUKS, a resize
of the filesystem on the (decrypted) block-device is attempted. This
should not be done, as the application that requested the Block volume
is the only authoritive reader/writer of the data.

In particular VirtualMachines that use RBD volumes as a disk, usually
have a partition table on the disk, instead of only a single filesystem.
The `resizefs` command will not be able to resize the filesystem on the
block-device, as it is a partition table.

When `resizefs` fails during NodeStageVolume, the volume is unstaged and
an error is returned.

Resizing an encrypted block-device requires `cryptsetup resize` so that
the LUKS header on the RBD-image is updated with the correct size. But
there is no need to call `resizefs` in this case.

b7703faf37 util: make inode metrics optional in FilesystemNodeGetVolumeStats()
CephFS does not have a concept of "free inodes", inodes get allocated
on-demand in the filesystem.

This confuses alerting managers that expect a (high) number of free
inodes, and warnings get produced if the number of free inodes is not
high enough. This causes alerts to always get reported for CephFS.

To prevent the false-positive alerts from happening, the
NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain
inodes in the reply anymore.

RBD mirroring functionality and hence the

c2280011d1 rbd: Report remote peer readiness if Up and status.Unknown
Current code uses an !A && !B condition incorrectly to
test A:Up and B:status for a remote peer image.

This should be !A || !B as we require both conditions to
be in the specified state (Up: true, and status Unknown).

This is corrected by this commit, and further fixes:
- check and return ready only when a remote site is
found in the status output
- check if all peer sites are ready, if multiple are found
and return ready appropriately

8d7b6ee59f rbd: consider mirror deamon state for ResyncVolume
During ResyncVolume we check if the image
is in an error state, and we resync.
After resync, the image will move to
either the `Error` or the `Resyncing` state.
And if the image is in the above two
conditions, we will return a successful
response and Ready=false so that the
consumer can wait until the volume is
ready to use. If the image is in any
other state we return an error message
to indicate the syncing is not going on.
The whole resync and image state change
depends on the rbd mirror daemon. If the
mirror daemon is not running, the image
can be in Resyncing or Unknown state.
The Ramen marks the volume replication as
secondary, and once the resync starts, it
will delete the volume replication CR as a
cleanup process.

As we dont have a check for the rbd mirror
daemon, we are returning a resync success
response and Ready=false. Due to this false
response Ramen is assuming the resync started
and deleted the volume replication CR, and
because of this, the cluster goes into a bad
state and needs manual intervention.

bc9ad3d9f1 rbd: add dummy attacher implementation
previously, it was a requirement to have attacher sidecar for CSI
drivers and there had an implementation of dummy mode of operation.
However skipAttach implementation has been stabilized and the dummy
mode of operation is going to be removed from the external-attacher.
Considering this driver  work on volumeattachment objects for NBD driver
use cases, we have to implement dummy controllerpublish and unpublish
and thus keep supporting our operations even in absence of dummy mode
of operation in the sidecar.

This commit make a NOOP controller publish and unpublish for RBD driver.

CephFS driver does not require attacher and it has already been made free
from the attachment operations.

8c5563a9bc rbd: remove checkHealthyPrimary check
After Failover of workloads to the secondary
cluster when the primary cluster is down,
RBD Image is not marked healthy, and VR
resources are not promoted to the Primary,
In VolumeReplication, the `CURRENT STATE`
remains Unknown and doesn't change to Primary.

This happens because the primary cluster went down,
and we have force promoted the image on the
secondary cluster. and the image stays in
up+stopping_replay or could be any other states.
Currently assumption was that the image will
always be `up+stopped`. But the image will be in
`up+stopped` only for planned failover and it
could be in any other state if its a forced
failover. For this reason, removing
checkHealthyPrimary from the PromoteVolume RPC call.

011d4fc81c cleanup: create k8s.io/mount-utils Mounter only once
Recently the k8s.io/mount-utils package added more runtime dectection.
When creating a new Mounter, the detect is run every time. This is
unfortunate, as it logs a message like the following:

```
mount_linux.go:283] Detected umount with safe 'not mounted' behavior
```

This message might be useful, so it probably good to keep it.

In Ceph-CSI there are various locations where Mounter instances are
created. Moving that to the DefaultNodeServer type reduces it to a
single place. Some utility functions need to accept the additional
parameter too, so that has been modified as well.

14ba1498bf util: reduce systemd related errors while mounting
There are regular reports that identify a non-error as the cause of
failures. The Kubernetes mount-utils package has detection for systemd
based environments, and if systemd is unavailable, the following error
is logged:

    Cannot run systemd-run, assuming non-systemd OS
    systemd-run output: System has not been booted with systemd as init
    system (PID 1). Can't operate.
    Failed to create bus connection: Host is down, failed with: exit status 1

Because of the `failed` and `exit status 1` error message, users might
assume that the mounting failed. This does not need to be the case. The
container-images that the Ceph-CSI projects provides, do not use
systemd, so the error will get logged with each mount attempt.

By using the newer MountSensitiveWithoutSystemd() function from the
mount-utils package where we can, the number of confusing logs get
reduced.

caf4090657 rbd: provide option to disable setting metadata on rbd images
As we added support to set the metadata on the rbd images created for
the PVC and volume snapshot, by default metadata is set on all the images.

As we have seen we are hitting issues#2327 a lot of times with this,
we start to leave a lot of stale images. Currently, we rely on
`--extra-create-metadata=true` to decide to set the metadata or not,
we cannot set this option to false to disable setting metadata because we
use this for encryption too.

This changes is to provide an option to disable setting the image
metadata when starting cephcsi.

3eb0fa5e21 rbd: fix parsing mapOptions
Currently, we support

mapOption: "krbd:v1,v2,v3;nbd:v1,v2,v3"

- By omitting `krbd:` or `nbd:`, the option(s) apply to
  rbdDefaultMounter which is krbd.
- A user can _override_ the options for a mounter by specifying `krbd:`
  or `nbd:`.
  mapOption: "v1,v2,v3;nbd:v1,v2,v3"
  is effectively the same as the 1st example.
- Sections are split by `;`.
- If users want to specify common options for both `krbd` and `nbd`,
  they should mention them twice.

But in case if the krbd or nbd specifc options contian `:` within them,
then the parsing is failing now.

GRPC error: badly formatted map/unmap options:
"krbd:read_from_replica=localize,crush_location=zone:zone1;"

This patch fix the above case where the options itself contain `:`
delimitor
ex: krbd:v1,v2,v3=v31:v32;nbd:v1,v2,v3"

Please note, if you are using such options which contain `:` delimiter,
then it is mandatory to specify the mounter-type.

4a69378698 rbd: introduce a helper function to detect multi writer,block & rwofile
SINGLE_NODE_WRITER capability ambiguity has been fixed in csi spec v1.5
which allows the SP drivers to declare more granular WRITE capability in form
of SINGLE_NODE_SINGLE_WRITER or SINGLE_NODE_MULTI_WRITER.

These are not really new capabilities rather capabilities introduced to
get the desired functionality from CO side based on the capabilities SP
driver support for various CSI operations, this new capabilities also help
to address new access mode RWOP (readwriteoncepod).

This commit adds a helper function which identity the request is of
multiwriter mode and also validates whether it is filesystem mode or
block mode. Based on the inspection it fails to allow multi write
requests for filesystem mode and only allow multi write request against
block mode.

This commit also adds unit tests for isMultiWriterBlock function which
validates various accesstypes and accessmodes.
