1. Ignore tables that use STI in reltuples count strategy.

   Models that use Rails' single-type inheritance, such as `Group` and
   `CiService`, need an additional WHERE clause to count the total
   properly, which isn't supported by the reltuples strategy.  For now,
   we just omit these from the statistics sampling and rely on the other
   strategies to get this data.

2. Fix tablesample count strategy not counting groups properly.

   Models such as `Group` needs a WHERE clause to distinguish it from
   namespaces. We now add in the WHERE clause if STI is in use.

Olliverschinagl/gitlab ce clarify master branch name

See merge request gitlab-org/gitlab-ce!25965

The 'master' branch name is confusing as it indicates some special branch name,
where it is actually just a 'ref'. 'branches' _is_ a special name as it
indicates 'all' branches.

Lets clarify the example a little to indicate this.

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.
