f2e0fa28fb deploy: allowPrivilegeEscalation: true in containerSecurityContext
When running the kubernetes cluster with one single privileged
PodSecurityPolicy which is allowing everything the nodeplugin
daemonset can fail to start. To be precise the problem is the
defaultAllowPrivilegeEscalation: false configuration in the PSP.
 Containers of the nodeplugin daemonset won't start when they
have privileged: true but no allowPrivilegeEscalation in their
container securityContext.

Kubernetes will not schedule if this mismatch exists cannot set
allowPrivilegeEscalation to false and privileged to true:

80dda7cc30 cephfs: detect corrupt ceph-fuse mounts and try to remount
Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.

This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

02bcb5f16a Enable leader election in v1.14+
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.

bd204d7d45 Use --keyfile option to pass keys to all Ceph CLIs
Every Ceph CLI that is invoked at present passes the key via the
--key option, and hence is exposed to key being displayed on
the host using a ps command or such means.

This commit addresses this issue by stashing the key in a tmp
file, which is again created on a tmpfs (or empty dir backed by
memory). Further using such tmp files as arguments to the --keyfile
option for every CLI that is invoked.

This prevents the key from being visible as part of the argument list
of the invoked program on the system.

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
