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

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.

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.

When the rbd-driver starts, it initializes some global (yuck!) variables

we added a workaround for rbd scheduling by creating
a dummy image in #2656. with the fix we are creating
a dummy image of the size of the first actual rbd
image which is sent in EnableVolumeReplication request
if the actual rbd image size is 1TiB we are creating
a dummy image of 1TiB which is not good. even though
its a thin provisioned rbd images this is causing
issue for the transfer of the snapshot during
the mirroring operation.
This commit recreates the rbd image with 1MiB size
which is the smaller supported size in rbd.

rbd mirroring CLI calls are async and it doesn't wait
for the operation to be completed. ex:- `rbd mirror image enable`
it will enable the mirroring on the image but it doesn't
ensure that the image is mirroring enabled and healthy
primary. The same goes for the promote volume also.
This commits adds a check-in PromoteVolume to make sure
the image in a healthy state i.e `up+stopped`.
note:- not considering any intermediate states to make
sure the image is completely healthy before responding
success to the RPC call.

Journal-based RADOS block device mirroring ensures point-in-time
consistent replicas of all changes to an image, including reads and
writes, block device resizing, snapshots, clones, and flattening.
Journaling-based mirroring records all modifications to an image in the
order in which they occur. This ensures that a crash-consistent mirror
of an image is available.
Mirroring when configured in journal mode, mirroring will
utilize the RBD journaling image feature to replicate the image
contents. If the RBD journaling image feature is not yet enabled on the
image, it will be automatically enabled.

Uses the below schema to supply mounter specific map/unmapOptions to the
nodeplugin based on the discussion we all had at
https://github.com/ceph/ceph-csi/pull/2636
This should specifically be really helpful with the `tryOthermonters`
set to true, i.e with fallback mechanism settings turned ON.
mapOption: "kbrd: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.
