ovs-vswitchd has arguments that are currently not exposed by
ovs-ctl as the project provided wrapper to start/stop the daemons.
This patch adds $OVS_VSWITCHD_OPTS which - if set - will be inserted in the
call to ovs-vswitchd as argument(s).
This avoids adding custom vars for each parameter that is there and
might be added.
