Oswaldo Ferreira bb8f2520b4 Persist truncated note diffs on a new table
We request Gitaly in a N+1 manner to build discussion diffs. Once the diffs are from different revisions, it's hard to make a single request to the service in order to build the whole response.
With this change we solve this problem and simplify a lot fetching this piece of info.
