Geo: Add a Geo Status Widget to Admin > Projects

What does this MR do?

Adds a Geo Status Widget to the Admin > Projects screen, allowing to easily interact with Geo replication from the project list in the Admin area.

This MR is based on the work from https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/7745 so please merge that first.

To be able to fit the same content on both the bigger and the smaller widget I had to reduce the amount of information we display from 4 columns to just 3. I've moved the retry count to the more section as it's only relevant when there is a failure. (See screenshots below)

What are the relevant issue numbers?

EE Backports:

• https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22124

(It's not possible to backport everything so test will still fail)
