qa/suites/rados: remove rook coverage from the rados suite
The rook team relies on a daily CI system to validate
rook changes. It doesn't seem that the teuthology tests
are maintained, so it makes sense to remove them from the
rados suite.
By removing this symlink, rook test coverage will remain
in the orch suite, and coverage will only be removed from the
rados suite.
