76064d8e34 cephfs: retry subvolumegroup creation
Incase the  subvolumegroup is deleted
and recreated we need to restart the
cephcsi provisioner pod to clear cache
that cephcsi maintains. With this PR
if cephcsi sees NotFound error duing
subvolume creation it will reset the cache
for that filesystem so that in next RPC
call cephcsi will try to create the
subvolumegroup again

3d3c029471 nfs: add nodeserver within cephcsi
This commit adds nfs nodeserver capable of
mounting nfs volumes, even with pod networking
using NSenter design similar to rbd and cephfs.
NodePublish, NodeUnpublish, NodeGetVolumeStats
and NodeGetCapabilities have been implemented.

The nodeserver implementation has been inspired
from https://github.com/kubernetes-csi/csi-driver-nfs,
which was previously used for mounted cephcsi exported
nfs volumes. The current implementation is also
backward compatible for the previously created
PVCs.

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.

ceb88d6498 cephfs: remove extra check for restore size
Looks like cephfs snapshot size is buggy and its
getting removed in ceph fs. we cannot get the size
of the snapshot during CreateVolume call, so we cannot
do any size check at CreateVolume to check if the
restore size is smaller or not.

As we are removing this check it also fixes #3147
but we dont have any validation at CSI level for
smaller restore we need to depend on kubernetes
external-provisioner for it.

permission to be on 777, however if we create a subvolume

set which is 755 for the subvolume. This commit try to stick
to the default behaviour even while creating the subvolume.

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.

When the image is force promoted to primary on the
cluster the remote image might not be in replaying
state because due to the split brain state. This
PR reverts back the commit
c3c87f2ef3. Which we added
to check the remote image status.
