Fix CephFS snapshot cloning scenario test

When unmounting a share with the kernel
client, the target directory must be what
we used during the mount operation.

This patch adds a create-share-from-snapshot
scenario test for the ceph-fuse client, and
drops the redundant 'ip_version' attribute
to test classes that was added in the
test reorganization patch earlier [1]
