seperate device owner flag for HA router interface port

[venkata anil]

Currently HA router interface port uses DEVICE_OWNER_ROUTER_INTF as device owner(like normal router interface). So to check if a port is a HA router interface port, we have to perform a DB operation.

Neutron server at many places(functions in plugin.py, rpc.py, mech_driver.py [1]) may need check if a port is HA router interface port and perform different set of operations, then it has to access DB for this. Instead if this information is available as port's device owner, we can avoid DB access every time.
