Subject: [PATCH] include/gitlab: Add functions for interacting with merge
 requests

To implement a bot that merges merge requests by majority decision,
functions are necessary to get details about merge requests.
This commit adds functions that allow the user to get the number of
members in a project, get details about the votes that have been cast
on a merge requests, add comments to merge requests, and merge merge
requests.
