One can now use the operator configmap for CSI_CLUSTER_NAME variable
for setting ClusterName on the RBD images and CephFS subvolume.
This will be useful in cases like for example, when two container orchestrator
clusters (Kubernetes/OCP) are using a single ceph cluster.

One can now tweak the operator configmap for CSI_ENABLE_METADATA boolean to
enable/disable setting of PV/PVC/PVCNamespace &
snapshot-name/snapshot-namespace/snapshotcontent-name on the RBD images
and CephFS subvolume.

CephFS CSI driver dont have/advertise controller publish/unpublish
capabilities, thus dont need attacher sidecar for its operations.
The presence of external-attacher adds on overhead and issues wrt
attachment in various scenarios. One of them would be the lack of
performance on syncing volumeattachment from api server..etc.
More or less we don't have controller publish and unpublish capabilities,
so we should not make use of this sidecar and cause
unnecessary addon here thus other issues.
similar changes have been added to CSI

This commit introduces new log level called csidecarLogLevel
for the sidecars which are not maintained by the csi-driver.
This will allow to have different configuration options
for the sidecars like snapshotter, resizer, attacher and
provisioner containers which will help to avoid the
spamming of logs to an extent.

A Liveness sidecar container that is deployed
with the CSI pods will be helpful to check
csi driver is properly responding or not.
and there is no liveness or readiness
kubernetes probe added for this one.
Providing an option to enable this
sidecar deployment and disabling it by default.

csi pods uses leader election and they were using
default values but seems like default values of leader
election are not working for some specific clusters.

If csi is configured not the use the
hostnetworking, deploy the holder
pod for executing the commands with nsenter.
The implementation is same as multus.

This argument in csi-provisioner and csi-snapshotter sidecar allows us
to receive additional metadata in the CreateVolume and CreateSnapshot()
request.
For ex:
as part of CreateVolume request:
csi.storage.k8s.io/pvc/name
csi.storage.k8s.io/pvc/namespace
csi.storage.k8s.io/pv/name
and
as part of CreateSnapshot request:
csi.storage.k8s.io/volumesnapshot/name
csi.storage.k8s.io/volumesnapshot/namespace
csi.storage.k8s.io/volumesnapshotcontent/name
This is useful information which can be used depend on the use case we have
at our csi driver level. The features like adding metadata to CephFS subvolume,
RBD image or snapshot can consume this based on the need.

Currently, the admin/user can configure the ceph.conf
for daemon pods using https://rook.io/docs/rook/v1.7/
ceph-advanced-configuration.html#custom-cephconf-settings.
This the above custom ceph.conf is only for ceph pods.
the support to provide constom ceph.conf for cephcsi
is added in cephcsi PR 2476
This PR adds the support to create/update

This commit introduces a new configuration option for
ceph csi driver to enable hostpath mounting of /etc/selinux
directory from the cluster node where csi plugin pods are
running, which inturn help the csi driver to specify
selinux-related mount options like context.
Ref# https://github.com/ceph/ceph-csi/issues/2295
The default value for this configuration is true and if cluster
nodes are running without selinux enabled, an admin can deploy
csi pods by specifying this option to `false` which skip the
host path mounting for the csi pods.

As like RBD, CephFS provisioner pod need not to
run as privileged. as its not doing any operation
like plugin pods which does mounting and unmounting
removing the permissions for the same.

Thanks to Golang 1.16, we can now embed files in the Go binary. This
means we don't need to add the CSI templates files to the container
image. They are added in the Go binary at build time.
The existing location of the template must be in the package calling it.
So they moved to pkg/operator/ceph/csi/template. All the files have been
symlinked back to cluster/examples/kubernetes/ceph/csi/template.
