host: Add kill_children utility method
This method is useful for killing the children spawned by
Popen() calls with shell=True. For instance:
proc = Popen('sleep 100', shell=True)
proc.kill()
This would spawn a shell task and that shell would spawn the sleep task.
Issuing a kill to the Popen handle will only kill the shell task,
and the sleep task will keep running.
Using host.kill_children(proc.pid) will ensure all child tasks are
killed.
