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.

While creating subvolumes, CephFS driver set the mode to `777`
and pass it along to go ceph apis which cause the subvolume
permission to be on 777, however if we create a subvolume
directly in the ceph cluster, the default permission bits are
set which is 755 for the subvolume. This commit try to stick
to the default behaviour even while creating the subvolume.
This also means that we can work with fsgrouppolicy set to
`File` in csiDriver object which is also addressed in this commit.

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)

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.
