refactor(backend): rename teardown_consolidated -> deprovision_consolidated

The backends' public teardown entry point now pairs with `launch_consolidated`
under the provision/deprovision verb used everywhere else
(`deprovision_bottle`, `deprovision_git_gate`). Renamed across all three
backends' consolidated_launch + launch modules and the tests.
