Below are the 3 different cases where we need

* CreateVolume:- Read the namespace from the

This commit ensures that parent image is flattened before
creating volume.
- If the data source is a PVC, the underlying image's parent
is flattened(which would be a temp clone or snapshot).
hard & soft limit is reduced by 2 to account for depth that
will be added by temp & final clone.
- If the data source is a Snapshot, the underlying image is
itself flattened.
hard & soft limit is reduced by 1 to account for depth that
will be added by the clone which will be restored from the
snapshot.
Flattening step for resulting PVC image restored from snapshot is removed.
Flattening step for temp clone & final image is removed when pvc clone is
being created.

SINGLE_NODE_WRITER capability ambiguity has been fixed in csi spec v1.5
which allows the SP drivers to declare more granular WRITE capability in form
of SINGLE_NODE_SINGLE_WRITER or SINGLE_NODE_MULTI_WRITER.
These are not really new capabilities rather capabilities introduced to
get the desired functionality from CO side based on the capabilities SP
driver support for various CSI operations, this new capabilities also help
to address new access mode RWOP (readwriteoncepod).
This commit adds a helper function which identity the request is of
multiwriter mode and also validates whether it is filesystem mode or
block mode. Based on the inspection it fails to allow multi write
requests for filesystem mode and only allow multi write request against
block mode.
This commit also adds unit tests for isMultiWriterBlock function which
validates various accesstypes and accessmodes.

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.

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.

This commit adds the logic to detect a passed in volumeID
is a migrated volume ID and if yes, the driver connect to the
backend cluster and clean/delete the image. The logic
only applied if its a migration volume ID. The migration volume ID
carry the information like mons, pool and image name which is
good enough for the driver to identify and connect to the backend
cluster for its operations.
migration volID format:
<mig>_mons-<monsHash>_image-<imageUID>_<poolHash>
Details on the hash values:
* MonsHash: this carry a hash value (md5sum) which will be acted as the
`clusterID` for the operations in this context.
* ImageUID: this is the unique UUID generated by kubernetes for the created
volume.
* PoolHash: this is an encoded string of pool name.

This commit adds capability to genVolFromVolumeOptions() to fetch
mapped clusted-id & mon ips for mirrored PVC on secondary cluster
which may have different cluster-id.
This is required for NodeStageVolume().
We also don't need to check for mapping during volume create requests,
so it can be disabled by passing a bool checkClusterIDMapping as false.
GetMonsAndClusterID() is modified to accept bool checkClusterIDMapping
based on which clustermapping is checked to fetch mapped cluster-id and
mon-ips.

Moving the log functions into its own internal/util/log package makes it

If the image is in a secondary state and its
up+replaying means its an healthy secondary
and the image is primary somewhere in the remote cluster
and the local image is getting replayed. Delete the
OMAP data generated as we cannot delete the
secondary image. When the image on the primary
cluster gets deleted/mirroring disabled, the image on
all the remote (secondary) clusters will get
auto-deleted. This helps in garbage collecting
the OMAP, PVC and PV objects after failback operation.
