Currently the Helm chart does not contain a
imagePullSecrets option when you are using
private container registry, this is very inconvenient.
This PR add this option for both CephFS and RBD.

Without this patch the READMEs for the Helm Charts do not provide any
documentation on how to upgrade to a newer version. There is at least
one known issue when updating to a newer versions that is unavoidable as
of writing. There is a workaround for the issue which should be
documented in the upgrade section.
This is a problem because currently the only way to find this workaround
is to go through closed GitHub issues. These might not be around at the
time someone needs this information. Furthermore the issue should be
communicated to the operator before it occurs.
This patch adds basic documentation for updating the Helm repository,
and upgrading the installed release of the Helm Chart. How values can be
set is not part of the documentation. If an operator used custom values,
e.g. for the secret, they probably already know how to deal with setting
values. However, the docs still remind the reader to take values into
account.
Reusing the installed values (`--reuse-values`) has lead to problems in
past, which is why it is explicitly discouraged. An example for this
would be the value `logLevel` which was changed to `sidecarLogLevel`.
Reusing values lead to `.Values.sidecarLogLevel` being empty and the
`csi-provisioner` not being started due to invalid value `-v=""`.
Comparing new values with set values is encouraged.
The workaround for issue #3397 from GitHub is being addressed in the
section Know Issues Upgrading.

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.

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:
