Deployment log #20
Description
This builds on a world view where deployments and builds are separate beings (see #15). The idea is similar to a git reflog, to track changes to the target of current.
Each deployment (in the sense of 'switching the target of current') should be logged with at least the following information:
- timestamp
git ref name (tag, branch, if any) and commit hash- build ID (includes information about the git ref)
- extra metadata that could be configured (e.g. username; hostname)
