Drop non-isolated dsvm jobs

Tempest provides three different credential providers for tests:
- dynamic credentials, which is what is used in all gate jobs
- preprovisioned credentials, which is used in experimental and
  periodic jobs, not yet in the gate because of bug 1524717
- legacy credentials, which relies on deprecated configuration
  options, and which is itself deprecated.

Support for those legacy settings is being removed from devstack
in I65b56ff681d6c27094380693c953fbc3664eceb0.

non-isolated jobs test the legacy credential provider, and should
be removed completely, as we do not want to maintain this
deprecated functionality anyways.
