Added Rubocop config for background migrations
This adds a Rubocop configuration file specific to
lib/gitlab/background_migrations. This configuration will be used to
(hopefully) make reviewing background migrations easier by enforcing
stricter rules compared to the rest of GitLab. Because this
configuration is directory specific it will only affect background
migrations.
