Rename `consolidated_util` -> `bottle_provision` and align it with
`gateway_provision` as the two provisioning domains: `bottle_provision` owns
the bottle lifecycle (`provision_bottle` + `deprovision_bottle`, the latter
renamed from `teardown_consolidated`), `gateway_provision` owns the git-gate
state pushed through the transport (`provision_git_gate`/`deprovision_git_gate`).
The three backends' consolidated_launch modules import from the new module;
their own public `teardown_consolidated` wrappers (called by launch.py) keep
their names.
