Use the new irqbalance plugin instead of a script to set up
irqbalance.
I'm placing the 'irqbalance' instance before the 'script' instance so
that it's executed at the same time as the script, however I don't
think the 'irqbalance' instance needs to be ordered in any specific
way and could be placed almost anywhere.

Realtime profiles require to restrict irqbalance too. Apply them to
the realtime profile so that realtime-virtual-{host|guest} can benefit
from that too.

In the cpu-partitioning profile, IRQ affinity change is already done
as part of the 'isolated_cores' option of the scheduler plugin, so
calling defirqaffinity is, at best, redundant. So let's remove the call.
In the realtime* profiles, it's essentially the same, except that tuna
was used instead of isolated_cores. So let's use built-in functionality
instead of tuna and drop calls to defirqaffinity.

Error message about no isolated cores set wasn't displayed,
because the current plugin_script code only logs messages written
to STDERR.
