Eric Leblond 789d46cc3c Add per-cpu prio handling
This patch updates affinity setting to add a support for per cpu
priority setting. In exclusive mode a thread is dedicated to a CPU.
This patch adds the ability to set the thread prio for all threads
of a family running on a given CPU.

With this patch we can write
    - detect_cpu_set:
        cpu: [ "all" ]
        mode: "exclusive" # run detect threads in these cpus
        low_prio: [ 0 ]
        medium_prio: [ "1-2" ]
        high_prio: [ 3 ]
With this configuration, detect threads assigned to cpu 0 will
have a low priority. Detect threads on cpus 1 and 2 will have
prio medium...

The previous configuration is equivalent to:
    - detect_cpu_set:
        cpu: [ "all" ]
        mode: "exclusive" # run detect threads in these cpus
        low_prio: [ 0 ]
        high_prio: [ 3 ]
        prio: "medium"
because the prio value is used a default.
