Plug-in for irqbalance settings management. The plug-in
configures CPUs which should be skipped when rebalancing IRQs in
`/etc/sysconfig/irqbalance`. It then restarts irqbalance if and
only if it was previously running.
The banned/skipped CPUs are specified as a CPU list via the
[option]`banned_cpus` option.
.Skip CPUs 2,4 and 9-13 when rebalancing IRQs
