Implements the client side for gitlab-org/gitaly#819. Which is a server
info command. This checks the server version and git binairy version on
the server.

A small UI was added for administrators, so they can check the status of
the Gitaly server. This is done for each storage the monolith knows.

Because of this commit, gitlab-org/gitlab-ce!15580 is now closed. That
MR removed the Git version too, but didn't replace it with anything.

I ran into some issues when trying it out

We can simplify the code quite a bit and improve performance by using
grape-entity merge fields:

https://github.com/ruby-grape/grape-entity/tree/v0.6.0#merge-fields

Relates to #42030

The group activity feed was limited to the first 20 projects found
in the group, which caused activity from some projects to be omitted.
A limit of 20 is applied to the query for events, so the
extra pagination does little in the way of performance.
