a151bec94b Use Deployment with leader election instead of StatefulSet
Deployment behaves better when a node gets disconnected from the rest of
the cluster - new provisioner leader is elected in ~15 seconds, while
it may take up to 5 minutes for StatefulSet to start a new replica.

Refer: 52d1fbcf9d

Fixes: #335

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

2d560ba087 update ceph-csi to build and use a single docker image
currently, we have 3 docker files(cephcsi,rbd,cephfs) in the ceph-csi repo.
[commit ](85e121ebfe)
added by John to build a single image which can act as rbd or
cephfs based on the input configuration.

This PR updates the makefile and kubernetes templates to use
the unified image and also its deletes the other two dockerfiles.

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

c6b4e47723 add if condition for attacher
adding the condition will help us
to easily remove the attacher later.
or even we can add else condition
if we have an alternate to attacher.
