Set up PostgreSQL database to store GitLab CE/EE test durations
We'd like to start regularly measure the time of the CI specs so that we can optimize our efforts towards reducing the total time of the test suite (from https://gitlab.com/gitlab-org/gitlab-ce/issues/24899#note_21233232 and https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/7854).
I think what we'll want is:
- A PostgreSQL database where a nightly CI task can store data
- Connect this database via Redash to graph and visualize the data
I'm thinking we could make this a public Redash site for everyone to view. That way we can enable everyone, including people from the community, to help.
