After this change we'll be able to push a tag to github to deploy to
collab.
The advantages of this are that there's no longer a separate step to
first
build the image, and then deploy it.
In the future I'd like to make this happen more automatically (maybe as
part of
bump nightly).
Release Notes:
- N/A
Also, move postgrest service + deployment into a separate manifest
file, which is deployed via a separate script, `deploy-postgrest`.
This way, we don't have unused postgrest instances in preview and
nightly, since those use the prod database.
