Show %CPU and %MEM for each node just below IP

[flaviostutz]

When looking at the dashboard and something is strange, I always have to look at the basic machine resources of each machine in order to verify if CPU and MEM are OK. Dashboard could just show this.

Something like:

    server-m1              server-m2
     manager                manager
    10.120.0.5              10.120.0.6
  c:10% m:45%       c:97% m:35%

|------------------|------------------|

(with a smaller letter, we can use cpu:10% mem:35% too)

What do you think? I could work on that if needed...
