Hemanth Nakkina 79db108e08 Fix removal of dvr-src mac flows when non-gateway port on router is deleted 
Removal of non-gateway port on DVR router deletes all the DVR to
SRC mac flows for the instances of same subnet on that compute node.
The instances are not reachable from any other network.

This patch checks if the DVR router port is gateway for the subnet
or not. And deletes the DVR-SRC mac flows only if it is gateway port.
The DVR-SRC mac flows are deleted if the gateway is not set for the subnet.

Conflicts:
    neutron/plugins/ml2/drivers/openvswitch/agent/ovs_dvr_neutron_agent.py
    neutron/tests/unit/plugins/ml2/drivers/openvswitch/agent/test_ovs_neutron_agent.py

arp_responder_enabled check added for the ARP flow rule.
The unit test case have arp_responder false by default, so adjusted
the br_int mock calls accordingly.
