Want systemd-cgtop like feature across nodes

[alexlarsson]

I.e. ability to get this kind of data from any node when you are on the manager node.

I'm not sure what apis systemd-cgtop uses, but it may very well be that it only uses the systemd properties that are already exposed by hirte, and all we need is a client application which collects this information.

Here is the cgtop code:
