Setup CI/CD for this repo

[sunker]

Currently, the only way to publish to npm and our github registry is by running

yarn build
yarn bundle 
npm publish  --access=public --scope=@grafana

This requires you to be logged into npm and to be part of the grafana org. Not sure exactly how, but I'd like these steps to be automated. See this PR to get an idea of how this has been solved in other repos at grafana.

For the backend, we could possibly have a bot create new releases every time we merge to the main branch. This is still TBD.

This should be done after this repo is split up in two. See this issue.

This was actually done with #30 and grafana/grafana-aws-sdk-react#1
