76ddf8e306 deploy: introduce new log level for sidecar controllers
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.

06c4477ff9 helm: 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

c9cc36d8db rbd: provide alternatives to preserve the ceph log files
Currently, we delete the ceph client log file on unmap/detach.

This patch provides additional alternatives for users who would like to
persist the log files.

Strategies:
-----------
`remove`: delete log file on unmap/detach
`compress`: compress the log file to gzip on unmap/detach
`preserve`: preserve the log file in text format

Note that the default strategy will be remove on unmap, and these options
can be tweaked from the storage class

Compression size details example:

On Map: (with debug-rbd=20)
---------
$ ls -lh

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.

--------
Provide a host path so that log directory is made available, and the
logs persist on the hostnode across container restarts.

b6a88dd728 rbd: add volume healer
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.

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.
