We do not want group level clusters to fall back to what was old
behaviour for project level clusters. So instead we will not return any
KUBE_TOKEN if we cannot find a suitable kubernetes_namespace for the
project, in the group level cluster case.

The numbers in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22650#note_117645395
are quite promising with that target.

This improves readability quite a bit.

A tablesample count executes in two phases:
* Estimate table sizes based on reltuples.
* Based on the estimate:
  * If the table is considered 'small', execute an exact relation count.
  * Otherwise, count on a sample of the table using TABLESAMPLE.

The size of the sample is chosen in a way that we always roughly scan
the same amount of rows (see TABLESAMPLE_ROW_TARGET).

The goal is to reflect separation of concern also in specs.

Fix line height of numbers in file blame view.
