c9e64f9478 deploy: make the csi-*plugin containers the default for kubectl commands
When issues or bugs are reported, users often share the logs of the
default container in a Pod. These logs do not contain the required
information, as that mostly only can be found in the logs of the
Ceph-CSI container (named csi-cephfsplugin or csi-rbdplugin).

By moving the Ceph-CSI containers in the Pods to the 1st in the list,
they become the default container for commands like `kubectl logs`.

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.

0be7024726 rbd: provide host-path for rbd-nbd logging
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.

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.

bd204d7d45 Use --keyfile option to pass keys to all Ceph CLIs
Every Ceph CLI that is invoked at present passes the key via the
--key option, and hence is exposed to key being displayed on

This commit addresses this issue by stashing the key in a tmp
file, which is again created on a tmpfs (or empty dir backed by
memory). Further using such tmp files as arguments to the --keyfile
option for every CLI that is invoked.

This prevents the key from being visible as part of the argument list
of the invoked program on the system.
