Migrate admin runner details from HAML to Vue
Background
In &4015 (closed) we describe and #299758 (closed) we will perform a series of improvements to the UX of the runner administration.
In parallel to the user facing improvements, we must also update the way the UI is built.
Description
The administration page in /admin/runners/<runner_id>
is used by administrators to manage a single runner.
Currently this view is simple implementation in static HAML. Although improvements are possible using this HAML, this view should be ported to Vue using a GraphQL API for us to move ahead with the major improvements that will proposed in #299758 (closed).
