Ramana Raja a232d273c1 qa/workunits/fs/snaps: allow tests to be run
... filesystems other than 'cephfs'.

It is not required to set  'allow_new_snaps' to True to allow snapshot
to be created on a filesystem. Remove that setting.

Remove 'fs/snaps/snaptest-0.sh' that is racy when running in parallel on
an another client that mounted the same file system. Include a similar
test in qa/tasks/cephfs/test_snapshots.py
