Geo: add secondary before db replication

See merge request gitlab-org/gitlab-ee!3274

As soon as the database is replicated the secondary will start behaving
as primary including attempting to write to the database which will fail
and cause errors. Moving this step prior avoids this.

Resolve "Improve code quality widget design"

Closes #2548

See merge request gitlab-org/gitlab-ee!3215

If using the old path (`/groups/$group/boards/*`), and there is no subgroup
called 'boards', redirect to `/groups/$group/-/boards/*`.

Note that because there is no path matching a group followed by an integer, this
redirect will work for individual boards even if there _is_ a subgroup called
'boards'.

Routes with the name `legacy_*_redirect` may have wildcards deliberately, in
order to support routing old paths to new paths. As long as these routes are
tested independently, they do not need to fail the path regex spec.

This returns the `real_size` of the MR's diff, which is a string indicating the
number of changes. If the diff overflows after _n_ files, the string will be
`$n+`.
