added missing fields to issue. Also, added a light url builder to add URLs easily from arel. Updated specs.

add pipeline id to merge request metrics table. Also, updated the pipeline worker to populate this field.

- Refactored cycle analytics class to extract DB logic
- Reuse logic in new events fetcher
- Started adding cycle analytics events class and spec (still not functional)

tests: Move rake assets:precompile and cloning gitlab-{shell,test} to the prepare stage
