[ovs-dev] [PATCH v2 RFC] ovs-lib: try to call exit before killing

[Ilya Maximets]

While killing OVS may not free all allocated resources.

Eample:
	Socket for vhost-user port will stay in a system
	after 'systemctl stop openvswitch' and opening
	that port after restart will fail.

version 2:
	* added '-T 1'
	* '-t $1' --> '-t $rundir/$1.$pid.ctl'
