Add ansible Galaxy remote type

- add ansible package type proxying the Galaxy v3 API
- rewrite href/links/download_url back to the remote so tarballs flow through it
- forward the query string for providers that opt in, keeping Galaxy pagination working
- add a UI usage snippet and an ansible e2e caching case
