Add ability to manage irqbalance on compute per role

Adds functionality whether to enable/disable irqbalance on compute
nodes.
Based on tuning recommendation for compute realtime nodes irqbalance
should be stopped and disabled. And tuned will be responsible for
managing IRQ balancing instead of irqbalance.
