[PATCH v8 17/18] virsh: Add support for throttle group operations

From: Chun Feng Wu <danielwuwy(a)163.com&gt; Implement new throttle cmds * Add new virsh cmds: domthrottlegroupset, domthrottlegrouplist, domthrottlegroupinfo, domthrottlegroupdel * Add doc for new cmds at docs/manpages/virsh.rst * Add cmd helper "virshDomainThrottleGroupCompleter", which is used by domthrottlegroupset, domthrottlegroupinfo, domthrottlegroupdel Signed-off-by: Chun Feng Wu <danielwuwy(a)163.com&gt; * Update of code documentation comments. * Reimplement Get throttle group from XML.
