- Use cache-control headers
- Update to rust nightly (for rust-analyzer and faster builds)
- Limit feeds to the last 20 posts:

- Use if-none-match to limit bandwidth further

Also does this:

- bump go_vanity to 0.3.0 and lets users customize the branch name
- fix formatting on jsonfeed
- remove last vestige of kubernetes/docker support
