Investigate increasing developer productivity with pull requests environments

[waveywaves]

I would like to make life easier for existing and new Redash contributors including maintainers by implementing Uffizzi previews. Disclaimer: I work on Uffizzi Uffizzi is a Open Source full stack previews engine and is free for Redash. This will provide newcomers with previews of their PRs in the cloud, allowing them iterate faster, without having to first set up a complete development environment themselves.

• [ ] Intial POC
