When dependabot creates a PR, and an other gets merged, the bot
automatically triggers a rebase. This will drop any approvals, causing
delays in the review/merge process.
The project uses Mergify to automatically rebase when needed, and
approvals are retained when Mergify rebases PR. By disabling the
auto-rebasing done by dependabot, fewer rebases should be needed,
contributors only need to review once, and CI jobs are triggered less
often.

This change allows the user to choose not to fallback to NBD mounter
when some ImageFeatures are absent with krbd driver, rather just fail
the NodeStage call.

Currently, we recognize and warn for the provided image features based on
our prior intelligence at ceph-csi (i.e based on supportedFeatures map
and validateImageFeatures) at image/PV creation time. It might be very
much possible that the cluster is heterogeneous i.e. the PV creation and
application container might both be on different nodes with different
kernel versions (krbd driver versions).
This PR adds a mechanism to check for the supported krbd features during
mount time, if the krbd driver doesn't have the specified image feature
then it will fall back to rbd-nbd mounter.

When using UPPER_CASE formatting for the HashiCorp Vault KMS
configuration, a missing `VAULT_DESTROY_KEYS` will cause the option to
be set to "false". The default for the option is intended for be "true".
This is a difference in behaviour between the `vaultDestroyKeys` and
`VAULT_DESTROY_KEYS` options. Both should use a default of "true" when
the configuration does not set the option explicitly.
By setting the default options in the `standardVault` struct before
unmarshalling the configuration in it, the default values will be
retained for the missing configuration options.

This commit adds a couple of helper functions to parse the migration
request secret and set it for further csi driver operations.
More details:
The intree secret has a data field called "key" which is the base64
admin secret key. The ceph CSI driver currently expect the secret to
contain data field "UserKey" for the equivalant. The CSI driver also
expect the "UserID" field which is not available in the in-tree secret
by deafult. This missing userID will be filled (if the username differ
than 'admin') in the migration secret as 'adminId' field in the
migration request, this commit adds the logic to parse this migration
secret as below:
"key" field value will be picked up from the migraion secret to "UserKey"
field.
"adminId" field value will be picked up from the migration secret to "UserID"
field
if `adminId` field is nil or not set, `UserID` field will be filled with
default value ie `admin`.The above logic get activated only when the secret
is a migration secret, otherwise skipped to the normal workflow as we have
today.

Thick-provisioning was introduced to make accounting of assigned space
for volumes easier. When thick-provisioned volumes are the only consumer
of the Ceph cluster, this works fine. However, it is unlikely that this
is the case. Instead, accounting of the requested (thin-provisioned)
size of volumes is much more practical as different types of volumes can
be tracked.
OpenShift already provides cluster-wide quotas, which can combine
accounting of requested volumes by grouping different StorageClasses.
In addition to the difficult practise of allowing only thick-provisioned
RBD backed volumes, the performance makes thick-provisioning
troublesome. As volumes need to be completely allocated, data needs to
be written to the volume. This can take a long time, depending on the
size of the volume. Provisioning, cloning and snapshotting becomes very
much noticeable, and because of the additional time consumption, more
prone to failures.

below are the local states of the mirrored image
"unknown" -> If the image is in an error state
means data is completely synced
"error" -> If the image is in an error state
means it needs resync
"syncing"
"starting_replay"
"replaying"
"stopping_replay"
"stopped"
If the resync is successfully started which
means the image will be in "replaying" state.
we can consider "replaying" state to report
resync succesfully going on state.
we are discarding the intermediate states like
"syncing", "starting_replay" and "stopping_replay".

After moving moving image to trash, if `trash remove` step fails,
then external-provisioner will issue subsequent requests, in which
image will be absent in pool( will be in trash) and omap cleanup will
be done with stale image left in trash with no `trash remove` step on it.
To avoid this scenario list trash images and find corresponding id for given
image name and add a task to flatten when we encounter a ErrImageNotFound.

Following the CSI specification, values that are included in the
VolumeUsage MUST NOT be negative. However, CephFS seems to return -1 for
the number of inodes that are available. Instead of returning a
negative value, set it to 0 so that it will not get included in the
encoded JSON response.

The command `vault monitor` can be used to stream logging from the Vault
service. This is very helpful while debugging Vault configuration
failures.
By adding a 2nd container to the Vault deployment, it is now possible to
get the messages from the Vault service by running
$ kubectl logs -c monitor <vault-pod-0123abcd>
This will be very useful when the e2e tests do not delete the deployment
after a failure and fetch the logs from all containers.

For static volume, the user will manually mounts
already existing image as a volume to the application
pods. As its a rbd Image, if the PVC is of type
fileSystem the image will be mapped, formatted
and mounted on the node,
If the user resizes the image on the ceph cluster.
User cannot not automatically resize the filesystem
created on the rbd image. Even if deletes and
recreates the kubernetes objects, the new size
will not be visible on the node.
With this changes During the NodeStageVolumeRequest
the nodeplugin will check the size of the mapped rbd
image on the node using the devicePath. and also
the rbd image size on the ceph cluster.
If the size is not matching it will do the file
system resize on the node as part of the
NodeStageVolumeRequest RPC call.
The user need to do below operation to see new size
* Resize the rbd image in ceph cluster
* Scale down all the application pods using the static
PVC.
* Make sure no application pods which are using the
static PVC is running on a node.
* Scale up all the application pods.
Validate the new size in application pod mounted
volume.
