Plugin scheduler now can do cores isolation on its own, Tuna is
not needed for it, e.g.:
[scheduler]
isolated_cores=2-4
ps_blacklist=.*pmd.*;.*PMD.*;^DPDK;.*qemu-kvm.*
It will isolate cores 2-4, it will ignore processes which matched
ps_blacklist regexes. Multiple regexes can be separated by ';'.
Quoted semicolon, i.e. '\;' is taken literally.
It also supports 'ps_whitelist' which is by default set to '.*'.
It takes all processes which matches ps_whitelist than it removes
those which matches ps_blacklist and move them out of the
isolated_cores. When the profile is unloaded it allows all matching
processes to run on all cores.
It changes processes affinities, threads affinities, IRQs affinities
and it sets default_smp_affinity for IRQs.
Also cpu-partitioning profile has been switched from Tuna to this
mechanism.
