[DDO-3289] Deploy Hook test mechanism

[jack-r-warren]

Adds endpoints to manually trigger deploy hooks. This is really just intended for test purposes, though I recognize that it could be misused. The endpoints require a minimal JSON body as protection against CSRF.

Testing

Mocked both Slack and GitHub to do this. Took quite a bit longer than writing the actual API endpoints, might not've bothered if I'd known it was going to take that long. Whatever, done now.

Risk

Extremely low
