Add feature flag to enforce gitaly request limits

See merge request gitlab-org/gitlab-ce!25931

We typically don't want to enforce request limits in production
However, we have some production-like test environments, i.e., ones
where `Rails.env.production?` returns `true`. We do want to be able
to check if the limit is being exceeded while testing in those
environments.
