Missing paths for interface virtual gateway address

[vsrx]

Similar to VRRP, vendors allow configuring a virtual gateway address on interfaces and looks like we are missing support for that in OC. Our current use case is for defining a VXLAN anycast gateway address.

Arista:

interface Vlan10
   ip address 10.1.1.1/24
   ip virtual-router address 10.1.1.254

Juniper:

interfaces {
    irb {
        unit 1 {
            proxy-macip-advertisement;
            virtual-gateway-accept-data;
            family inet {
                address 10.1.1.1/24 {
                    virtual-gateway-address 10.1.1.254;
                }
            }
        }
}
