refactor(backend): verb-first names for the provisioning modules

Rename the module files to match their functions' verb-first names:
`bottle_provision.py` -> `provision_bottle.py`,
`gateway_provision.py` -> `provision_gateway.py` (and the test file to match).
Imports, docstrings, and the git_gate/service.py pointer updated.
