Major overhaul on acceptance test infrastructure and ci pipeline

- Intent is to deploy this to the shared foundational infrastructure ci instance
- As there is no longer a long lived bosh director, the acceptance tests now run in a bosh-lite environment directly in the CI container
- CI has jobs for acceptance tests, automated weekly bumps for golang packages, automated bumps of postgres packages, and a job to cut a final release
- All other CI pipelines and tasks have been removed
- Acceptance tests have been updated to go mod and dependencies have been vendored
- I've removed the "old" concept from the versions.yml and instead changed the helper
  to use the release two versions back as the old one. Not 100% sure this is correct
  behavior (and may cause problems due to v45 being broken), but it seems like
  testing n-2 to current will always catch problems caused by a major postgres bump.
