@susodapop as you said, this PR only adds support for NewRelic DataSource.

@mudasirmirza , thanks for the PR! We've updated a lot of things now that we're Community-driven so - if you're still interested in getting this merged - would you mind rebasing off master to re-run the CI, as well as updating merge conflicts?

We're trying to clean up our PR todo list, so if you're not interested, that's fine - we'll close the PR in about a week if we don't hear back. If you're interested in reopening the PR afterwards, we would also very much welcome that.

I've just solved the merge conflict (it was just a 1-liner), but there looks to be other problems that need fixing as well.

Hopefully @mudasirmirza still has the time and interest to get this PR done. 😄
