Feature: CI/CD, Pull request QC and directives

[Magnus167]

Pull request titles are essential to conveying version history for features as well as documenting changes. They are also used for generating release notes and developer logs (see #1070).
This PR introduces tests that assert a logical naming convention to PR titles.
This PR also introduces PR directives, which effectively allow the author to block/automatically approve merges depending on another PRs status.
