Merge branch 'rs-reference-filters' into 'master' 

Convert GFM reference handling to html-pipeline filters

- `Gitlab::Markdown` is now much cleaner
- Better separation of concerns
- Cleaner, less brittle, more maintainable specs for each reference type.
- Label references actually work!

- !123 : for merge requests
- $123 : for snippets
- 1234567 : for commits
