This is step 1 implementation of OFAgent l2-population. OFAgent partially uses codes in OVS agent on implementation of l2-population. We share these codes adding mixin class for OVS to l2-population rpc. We use a ryu library instead of executing a ovs-vsctl command and on OFAgent l2-population is no longer optional. Also a function of local arp responder will be implemented on step 2. related commit: b6133c35dd587f6b01e8ec12757347b2767713a6 Partially implements: blueprint ofagent-l2pop Change-Id: I99a2adfd380a9fefe34c53e0dabc21d8cf5936cc
