This commit adds locks on reclaimspace operations to
prevent multiple process executing rbd sparsify/fstrim
on same volume.

In the future we'll introduce a more standard interface for objects like
Volumes and Snapshots. It is useful to have the context passed as 1st
argument to all functions of those objects, including their Destroy()
function.

This commit makes sure sparsify() is not run when rbd
image is in use.
Running rbd sparsify with workload doing io and too
frequently is not desirable.
When a image is in use fstrim is run and sparsify will
be run only when image is not mapped.

blkdiscard cmd discards all data on the block device which
is not desired. Hence, return unimplemented code if the
volume access mode is block.

The CSI Controller (provisioner) can call `rbd sparsify` to reduce the
space consumption of the volume.
