caf4090657 rbd: provide option to disable setting metadata on rbd images
As we added support to set the metadata on the rbd images created for
the PVC and volume snapshot, by default metadata is set on all the images.

As we have seen we are hitting issues#2327 a lot of times with this,
we start to leave a lot of stale images. Currently, we rely on
`--extra-create-metadata=true` to decide to set the metadata or not,
we cannot set this option to false to disable setting metadata because we
use this for encryption too.

This changes is to provide an option to disable setting the image
metadata when starting cephcsi.

1da446d2f2 rbd: healer detect Kubernetes version for right StagingTargetPath
Kubernetes 1.24 and newer use a different path for staging the volume.
That means the CSI-driver is requested to mount the volume at an other
location, compared to previous versions of Kubernetes. CSI-drivers
implementing the volumeHealer, must receive the correct path, otherwise
the after a nodeplugin restart the NBD mounts will bailout attempting
to NodeStageVolume() call and return an error.

74965fef41 deploy: fix default URL for --csi-addons-endpoint option
The --csi-addons-endpoint= option has been added recently, but was not
configured in the deployment files yet. The socket was incorrectly
created as `/csi-addons.sock`, by correcting the URL to the socket, the
socket now gets created as `/tmp/csi-addons.sock` in the same directory
as other sockets.

If an endpoint is a UNIX Domain Socket, the format needs to be
`unix:///path/to/socket`. The `unix://` URL format allows an
authentication provider to be added directly after the `//`. If there is
no authentication provider needed, the field can remain empty. After the
authetication provider, the full path needs to be specified, starting
with a `/`. This means that URLs to a UDS should start with `unix:///`
in normal cases.

203920d8f4 rbd: move driver component into the rbd/driver package
The rbd package contains several functions that can be used by
CSI-Addons Service implmentations. Unfortunately it is not possible to
do this, as the rbd-driver needs to import the csi-addons/rbd package to
provide the CSI-Addons server. This causes a circular import when
services use the rbd package:

 - rbd/driver.go import csi-addons/rbd
 - csi-addons/rbd import rbd (including the driver)

By moving rbd/driver.go into its own package, the circular import can be
prevented.

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.

start flattening the older snapshots and
returns the ABORT error message, The Request
comes after this as to wait till all the
images are flattened (this will increase the
PVC creation time.  Instead of waiting till
the maximum snapshots on an RBD image, we can
have a soft limit, once the limit reached
cephcsi will start flattening the task to
break the chain. With this PVC  creation time
will only be affected when the hard limit
(minsnapshotsonimage) reached.
