9a03d735a2 Remove redundant pool parameter from snapshot class
The SnapshotClass for RBD requires a pool parameter. This is redundant
as a snapshot is not created on a different pool than the source image
of the snapshot (refer rbd man page).

Further, when a snapshot needs to be created its source CSI VolumeID
is passed to the creation call, and hence the source volumes pool
needs to be reused to create the snapshot.

Similarly to clone a snapshot, the create request would come in with a
SnapshotID to help identify the snapshot pool, and the same create
request parameters would contain the storage class based pool parameter
to create the clone into (as clones can be in different pools as
compared to their parent snapshots).

Thus, the parameter pool seems redundant in the snapshot class and
should be removed to improve ease of use.

Fixes #379

d02e50aa9b Removed config maps and replaced with rados omaps
Existing config maps are now replaced with rados omaps that help
store information regarding the requested volume names and the rbd
image names backing the same.

Further to detect cluster, pool and which image a volume ID refers
to, changes to volume ID encoding has been done as per provided
design specification in the stateless ceph-csi proposal.

Additional changes and updates,
- Updated documentation
- Updated manifests
- Updated Helm chart
- Addressed a few csi-test failures

97f8c4b677 Provide options to pass in Ceph cluster-id
This commit provides the option to pass in Ceph cluster-id instead
of a MON list from the storage class.

This helps in moving towards a stateless CSI implementation.

Tested the following,
- PV provisioning and staging using cluster-id in storage class
- PV provisioning and staging using MON list in storage class

Did not test,
- snapshot operations in either forms of the storage class
