[ovs-discuss] Remote connection method for ovn-controller ovs-ofctl invocation.

Currently in Openvswitch-2.7.1, ovn-controller hard codes connection method for ovs-ofctl invokation as unix:file as  assumption is  there will be unix file created by vswitchd in OVS_RUNDIR for managing OF controller on bridge e.g. br-int.mgmt

There is an issue in our Openvswitch offload model where  vswitchd is running on nic  and ovn-controller on host.  As there is no option for telling ovn-controller to use tcp:port connection method for ovs-ofctl , flows are not being pushed to vswitchd.

For providing the patch, need some input. Should connection method be provided as an argument to ovn-controller or it can be written to /etc/sysconfig/openvswitch from where ovn-controller can read and use if option is present otherwise it defaults to unix file method.
