a1ed6207f6 cephfs: report detailed error message on clone failure
go-ceph provides a new GetFailure() method to retrieve details errors
when cloning failed. This is now included in the `cephFSCloneState`
struct, which was a simple string before.

While modifying the `cephFSCloneState` struct, the constants have been
removed, as go-ceph provides them as well.

c9943320ac cephfs: skip NetNamespaceFilePath if the volume is pre-provisioned
In case of pre-provisioned volume the clusterID is
not set in the volume context as the clusterID is missing
we cannot extract the NetNamespaceFilePath from the
configuration file. For static volume and dynamically
provisioned volume the clusterID is set.

Note:- This is a special case to support mounting PV
without clusterID parameter.

80dda7cc30 cephfs: detect corrupt ceph-fuse mounts and try to remount
Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.

This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

aa6297e164 cleanup: refactor helper functions in nodeserver.go
Refactored a couple of helper functions for easier resue.

* Code for building store.VolumeOptions is factored out into a separate function.

* Changed args of getCredentailsForVolume() and NodeServer.mount() so that
  instead of passing in whole csi.NodeStageVolumeRequest, only necessary
  properties are passed explicitly. This is to allow these functions to be
  called outside of NodeStageVolume() where NodeStageVolumeRequest is not
  available.

9d1e98ca60 rbd: check for clusterid mapping in genVolFromVolumeOptions()
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.
