John Ferlan 1cfc0a9990 virsh: Add iothreadpin command
https://bugzilla.redhat.com/show_bug.cgi?id=1135491

$ virsh iothread --help

  NAME
    iothreadpin - control domain IOThread affinity

  SYNOPSIS
    iothreadpin <domain> <iothread> <cpulist> [--config] [--live] [--current]

  DESCRIPTION
    Pin domain IOThreads to host physical CPUs.

  OPTIONS
    [--domain] <string>  domain name, id or uuid
    [--iothread] <number>  IOThread ID number
    [--cpulist] <string>  host cpu number(s) to set
    --config         affect next boot
    --live           affect running domain
    --current        affect current domain

Using the output from iothreadsinfo, allow changing the pinned CPUs for
a single IOThread.

$ virsh iothreadsinfo $dom
 IOThread ID    CPU Affinity
---------------------------------------------------
 1               2
 2               3
 3               0-1

$ virsh iothreadpin $dom 3 0-2

Then view the change

$ virsh iothreadsinfo $dom
 IOThread ID    CPU Affinity
---------------------------------------------------
 1               2
 2               3
 3               0-2

If an invalid value is supplied or require option missing,
then an error will be displayed:

$ virsh iothreadpin $dom 4 3
error: invalid argument: iothread value out of range 4 > 3

$ virsh iothreadpin $dom 3
error: command 'iothreadpin' requires <cpulist> option
