Subject: [PATCH] Move real data jobs nodeset to three nodes (two computes + 1
 controller)

ceilometer-acompute and n-cpu disabled by default and only enabled on
compute nodes.

Execution time of real jobs increased to 8 minutes to allow CPU and RAM
metrics to reach the final value so prometheus query (mean) will return
valid values

New node set added with three nodes
