Move mounting staging instance to a sub-path within staging path

Browse Source 
This commit moves the mounting of a block volumes and filesystems
to a sub-file (already the case) or a sub-dir within the staging
path.

This enables using the staging path to store any additional data
regarding the mount. For example, this will be extended in the
future to store the fsid of the cluster, and maybe the pool name
to map unmap requests to the right image.

Also, this fixes the noted hack in the code, to determine in a
common manner if there is a mount on the passed in staging path.
