203920d8f4 rbd: move driver component into the rbd/driver package
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.

9a4533e549 rbd: create 1MiB size dummy image
we added a workaround for rbd scheduling by creating
a dummy image in . 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.

e7d8834149 rbd: enabe journal based mirroring
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.

027b68ab39 rbd: operate on dummy image after adding scheduling
currently we are fist operating on the  dummy
image to refresh the pool and then we are adding
the scheduling. we think the scheduling should
be added first and than we should refresh the
pool. If we do this all the existing schedules
will be considered from the scheduler.

bdcf3273b5 rbd: provide a way to supply mounter specific mapOptions from sc
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.
