Show quota status in the admin panel

[olevski]

It can happen that a quota is full. And it may be hard for an admin to realize this from just using kubectl.

In the admin panel we can show information about the status of a quota.

Probably easiest to not keep updating this information all the time but to have a button the admin can press to refresh the info. At least to start. Then we can make it fancier.

This needs an update on the backend too so that we can not only show the resources that the quota limits/restricts but also its status from k8s which will show how much of the resources in the quota are available or taken up.

There is a pitch to do this already written! :)
