Display publishing status in repositories tab

[hellcp-work]

Is your feature request related to a problem? Please describe.
The information about publishing status is available in multiple views, namely the project and package show, as well as project monitor. That information however is also relevant for when the repositories are being modified in the repositories tab. Include that information in the repository tab as well.

Describe the solution you'd like
Display a small indicator of the repository status next to the repository architecture
