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.

in NodeStage RPC call we have to map the
device to the node plugin and make sure the
the device will be mounted to the global path
in nodeUnstage request unmount the device from
global path and unmap the device
if the volume mode is block we will be creating
a file inside a stageTargetPath and it will be
considered as the global path

Currently the cephfs PVC create/delete and all other operations
related to cephfs are failing. One of the recent commits in rook
900abbc967e108ad622648b740a7c57f1268209f has modified ceph-mgr
to run as ceph user rather than root user. The ceph user currently
has no permission to write to the root of the cephfs filesystem.
The fix will be external to CSI itself, but until that lands, sending
a workaround patch so the CSI CI is unblocked
In this patch, we are setting the permission 777 on root of the cephfs
filesystem. Thus ceph user will be able to modify the cephfs filesystem.

RBD plugin needs only a single ID to manage images and operations against a
pool, mentioned in the storage class. The current scheme of 2 IDs is hence not
needed and removed in this commit.
Further, unlike CephFS plugin, the RBD plugin splits the user id and the key
into the storage class and the secret respectively. Also the parameter name
for the key in the secret is noted in the storageclass making it a variant and
hampers usability/comprehension. This is also fixed by moving the id and the key
to the secret and not retaining the same in the storage class, like CephFS.
Fixes#270
Testing done:
- Basic PVC creation and mounting
