ShyamsundarR b9cd0e18ad Make CephFS plugin stateless reusing RADOS based journal scheme
This is a part of the stateless set of commits for CephCSI.

This commit removes the dependency on config maps to store cephFS provisioned
volumes, and instead relies on RADOS based objects and keys, and required
CSI VolumeID encoding to detect the provisioned volumes.

Changes:
- Provide backward compatibility to provisioned volumes by older plugin versions (1.0.0 or older)
- Remove Create/Delete support for statically provisioned volumes (fixes #382)
- Added namespace support to RADOS OMaps and used the same to store RADOS CSI objects and keys in the CephFS metadata pool
- Added support to mention fsname for CephFS provisioning (fixes #359)
- Changed field name in CSI Identifier to 'location', to denote a pool or fscid
- Updated mounter cache to use new scheme
- Required Helm manifests are updated
- Required documentation and other manifests are updated
- Made driver option 'metadatastorage' as optional, as fresh installs do not need to specify the same

Testing done:
- Create/Mount/Delete PVC
- Create/Delete 5 PVCs
- Mount version 1.0.0 PVC
- Delete version 1.0.0 PV
- Mount Statically defined PV/PVC/Pod
- Mount Statically defined version 1.0.0 PV/PVC/Pod
- Delete Statically defined version 1.0.0 PV/PVC/Pod
- Node restart when mounted to test mountcache
- Use InstanceID other than 'default'
- RBD basic round of tests, as namespace is added to OMaps
- csitest against ceph-fs plugin
  - NOTE: CephFS plugin still does not detect and address already created
  volumes but of a different size
- Test not providing any value to the metadata storage parameter

# This is a sample config map that helps define a Ceph cluster configuration

apiVersion: v1
kind: ConfigMap
# The <cluster-id> is used by the CSI plugin to uniquely identify and use a
# Ceph cluster, the value MUST match the value provided as `clusterID` in the
# StorageClass
# The <MONValue#> fields are the various monitor addresses for the Ceph cluster
# identified by the <cluster-id>
# If a CSI plugin is using more than one Ceph cluster, repeat the section for
# each such cluster in use.
# To add more clusters or edit MON addresses in an existing config map, use
# the `kubectl replace` command.
# NOTE: Changes to the config map is automatically updated in the running pods,
# thus restarting existing pods using the config map is NOT required on edits
# to the config map.
