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.

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.

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

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.

There are regular reports that identify a non-error as the cause of
failures. The Kubernetes mount-utils package has detection for systemd

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.

If the volume with a bigger size is created
from a snapshot or from another volume we
need to exapand the filesystem also in the
csidriver as nodeExpand request is not triggered
for this one, During NodeStageVolume we can
expand the filesystem by checking filesystem
needs expansion or not.
If its a encrypted device, check the device
size of rbd device and the LUKS device if required
the device will be expanded before
expanding the filesystem.

dummy image rbdVolume struct is derived
from the actual one rbdVolume of the
volumeID sent in the EnableVolumeReplication
request. and the dummy rbdVolume struct contains
the image id of the actual volume because
of that when we are repairing the dummy
image the image is sent to trash but not
deleted due to the wrong image ID. resetting
the image id will makes sure the image id
is fetching from ceph cluster and same
image id will be used for manager operation.

IsBlockMultiNode() is a new helper that takes a slice of
VolumeCapability objects and checks if it includes multi-node access
and/or block-mode support.
This can then easily be used in other services that need checking for
these particular capabilities, and preventing multi-node block-mode
access.

we have added clusterID mapping to identify the volumes
in case of a failover in Disaster recovery in #1946.
with #2314 we are moving to a configuration in
configmap for clusterID and poolID mapping.
and with #2314 we have all the required information
to identify the image mappings.
This commit removes the workaround implementation done
in #1946.

The rbd package contains several functions that can be used by
CSI-Addons Service implmentations. Unfortunately it is not possible to
do this, as the rbd-driver needs to import the csi-addons/rbd package to
provide the CSI-Addons server. This causes a circular import when
services use the rbd package:
- rbd/driver.go import csi-addons/rbd
- csi-addons/rbd import rbd (including the driver)
By moving rbd/driver.go into its own package, the circular import can be
prevented.

HexStringToInteger() used to return a uint64, but everywhere else uint
is used. Having HexStringToInteger() return a uint as well makes it a

When the rbd-driver starts, it initializes some global (yuck!) variables
in the rbd package. Because the rbd-driver is moved out into its own
package, these variables can not easily be set anymore.
Introcude SetGlobalInt(), SetGlobalBool() and InitJournals() so that the
rbd-driver can configure the rbd package.

NodeServer.mounter is internal to the NodeServer type, but it needs to
be initialized by the rbd-driver. The rbd-driver is moved to its own
package, so .Mounter needs to be available from there in order to set
it.

The dummy image will be created with 1Mib size.
during the snapshot transfer operation the 1Mib
will be transferred even if the dummy image doesnot
contains any data. adding the new image features
`fast-diff,layering,obj-map,exclusive-lock`on the
dummy image will ensure that only the diff is
transferred to the remote cluster.
