Title: Feature/mr labels

## What does this MR do?
Implements labels for merge requests. It unifies the labels between issues and merge requests - if a label is added to an issue that same label will be visible in the merge requests tab as well. There's enough similarity between MRs and issues I didn't think it made sense to separate the labels.

## Are there points in the code the reviewer needs to double check?
See code comments.

## Why was this MR needed?
Labels have been available on issues for some time. It would really be nice to have them available for MRs, too. It's also been a feature request for about a year.

## What are the relevant issue numbers / Feature requests?
