deploy only tagged commits

[rsyring]

Right now, deploy builds the image from the current disk's file and uses the timestamp for the tags. That's fine for iterative development but when working with prod or beta, we'd want to be able to control the deploy more.

• Build/push docker images as part of CI for branches/PR. Every commit or just tagged ones? Maybe only versioned commits which indicates we want to run the branch in AWS for QA?
• Create some kind of release command that sets the version on master and then deploys. Potentially integrate with GH actions.
