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.

For JSON requests epics index page returns a JSON array of epics. This
will be used on epic roadmap page (#3559). Pagination is disabled in
this case - it's not supported for the first iteration on roadmap page.

Until now JSON response for epics index action returned an HTML list of
epics but it was not used anywhere in our code.

On epics roadmap page we list all epics in the given time frame
without pagination (at least for the first iteration), in this
case it would be nice to use the existing issuables index logic
except pagination (see MR gitlab-ee!4281). For this reason this
patch allows to easily disable pagination.

When listing epics in a group, include also epics from all group's
subgroups. Also `by_iids` filter is removed from EpicsFinder because
filtering by iid (which is scoped to single group) doesn't make sense
since subgroups are included too.
