This commit change the default fsgroup policy for csi driver object
to "File" type which is the better/correct setting for the CSI volumes.
We have been using default value which is "ReadWriteOnceWithFSType".
with this change backward compatibility should be preserved.

At present we have single log level configuration for all the containers
running for our CSI pods, which has been defaulted to log Level 5.
However this cause many logs to be spitted in a cluster and cause log
spamming to an extent. This commit introduce one more log level control
for CSI pods called sidecarLogLevel which defaults to log Level 1.
The sidecar controllers like snapshotter, resizer, attacher..etc has
been configured with this new log level and driver pods are with old
configruation value.
This allow us to have different configuration options for sidecar
constrollers and driver pods.
With this, we will also have a choice of different configuation setting
instead of locking onto one variable for the containers deployed via CSI driver.
To summarize the CSI containers maintained by Ceph CSI driver has log
level 5 and controllers/sidecars not maintained by Ceph CSI driver has
log level 1 configuration.

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:

This argument in csi-snapshotter sidecar allows us to receive
snapshot-name/snapshot-namespace/snapshotcontent-name metadata in the
CreateSnapshot() request.
For ex:
csi.storage.k8s.io/volumesnapshot/name
csi.storage.k8s.io/volumesnapshot/namespace
csi.storage.k8s.io/volumesnapshotcontent/name
This is a useful information which can be used depend on the use case we
have at our driver. The features like adding metadata to snapshot image
can consume this based on the need.

With Amazon STS and kubernetes cluster is configured with
OIDC identity provider, credentials to access Amazon KMS
can be fetched using oidc-token(serviceaccount token).
Each tenant/namespace needs to create a secret with aws region,
role and CMK ARN.
Ceph-CSI will assume the given role with oidc token and access
aws KMS, with given CMK to encrypt/decrypt DEK which will stored
in the image metdata.

The generated files under the deploy/ directory contain an empty YAML

the unneeded `---` start of the file for the header should make parsing

Problem:
--------
1. rbd-nbd by default logs to /var/log/ceph/ceph-client.admin.log,
Unfortunately, container doesn't have /var/log/ceph directory hence
rbd-nbd is not logging now.
2. Rbd-nbd logs are not persistent across nodeplugin restarts.
Solution:
--------
Provide a host path so that log directory is made available, and the
logs persist on the hostnode across container restarts.

Problem:
-------
For rbd nbd userspace mounter backends, after a restart of the nodeplugin
all the mounts will start seeing IO errors. This is because, for rbd-nbd
backends there will be a userspace mount daemon running per volume, post
restart of the nodeplugin pod, there is no way to restore the daemons
back to life.
Solution:
--------
The volume healer is a one-time activity that is triggered at the startup
time of the rbd nodeplugin. It navigates through the list of volume
attachments on the node and acts accordingly.
For now, it is limited to nbd type storage only, but it is flexible and
can be extended in the future for other backend types as needed.
From a few feets above:
This solves a severe problem for nbd backed csi volumes. The healer while
going through the list of volume attachments on the node, if finds the
volume is in attached state and is of type nbd, then it will attempt to
fix the rbd-nbd volumes by sending a NodeStageVolume request with the
required volume attributes like secrets, device name, image attributes,
and etc.. which will finally help start the required rbd-nbd daemons in
the nodeplugin csi-rbdplugin container. This will allow reattaching the
backend images with the right nbd device, thus allowing the applications
to perform IO without any interruptions even after a nodeplugin restart.

Nodeplugin needs below cluster roles:
persistentvolumes: get
volumeattachments: list, get
These additional permissions are needed by the volume healer. Volume healer
aims at fixing the volume health issues at the very startup time of the
nodeplugin. As part of its operations, volume healer has to run through
the list of volume attachments and understand details about each
persistentvolume.
The later commits will use these additional cluster roles.
