      Migrate MR commits and diffs to new tables · f2d50af9
      Sean McGivern authored
      Previously, we stored these as serialised fields - `st_{commits,diffs}` - on the
      `merge_request_diffs` table. These now have their own tables -
      `merge_request_diff_{commits,diffs}` - with a column for each attribute of the
      serialised data.
      
      Add a background migration to go through the existing MR diffs and migrate them
      to the new format. Ignore any contents that cannot be displayed. Assuming that
      we have 5 million rows to migrate, and each batch of 2,500 rows can be
      completed in 5 minutes, this will take about 7 days to migrate everything.
