CORD-512 Support vSG <-> vRouter default route

- Support multiple subnets per port. getIpPort() will only return the first non-/32 and non-/0 subnet
    /32 is used as vSG subnet
    /0 is used as default gateway
- Support multiple L3 unicast group on a single port
    Change the way to generate the group ID and group key
- Special case for 0.0.0.0 host. Push a /0 to IP table instead of /32
- Implement vRouterConfig
    Put VR MAC to TMAC table of all leaves when config added
        When processEthDst see PortNumber.ANY in key, match ETH_DST only
- For OFDPA, wipe existing instruction before sending to controller
    So packet that misses L3 unicast table won't be sent to controller twice
- For SpringOpenTTP, pop VLAN before sending to controller
- Move several constant definitions to SegmentRoutingService
- Add minimum priority for IP rules such that /0 won't collide with zero priority default rules
- Update the config sample
    Use VLAN=-1 for hosts
    Add example for default route
