Allow setting feature flags per GitLab group

See merge request gitlab-org/gitlab-ce!25022

are for batch updating pre-registered collections.

Allow blank values to be stored in reactive cache

See merge request gitlab-org/gitlab-ce!25283

Reactive caching concern was using .present? to determine if it got
a valid value from the cache. This returns false for values such as
false, [], {}. Change this check to !.nil? instead.

These specs were flaky and only passing after a retry due to how
rspec-retry works.

1. The test with paths that don't exist was returning 200 on the first
  try, then 404 on the second, not because the paths don't exist, but
  because the MR IID didn't change, thus the MR couldn't be found.
  I decided to remove the test entirely since we don't seem to return
  404 for paths that don't exist.
2. The test with a user that cannot view the merge request was failing
  the first time because the project owner wasn't removed with
  `project.team.truncate`.
  Changing the `let(:user)` to `create(:user)` and calling
  `project.add_maintainer(user)` in the `before` block fix the test.
