Remove novaclient CLI tests

These have been converted to novalclient functional tests
(I5a34cf1a39d4f73f94a27cce365434bd4a0eea0b).  The CLI tests never really
made a lot of sense as part of tempest itself, and now that we have
tempest-lib and other bits in place to enable functional testing we can
start moving each of these CLI tests into there respective repos.
