Subject: yang: update zebra interface model

Modify interface config model
and add zebra specific interface state operational data.

augment /frr-interface:lib/frr-interface:interface:
  +--rw zebra
     +--rw ip-addrs* [address-family ip-prefix]
     |  +--rw address-family    identityref
     |  +--rw ip-prefix         ietf-inet-types:ip-prefix
     |  +--rw label?            string
     |  +--rw ip4-peer?         ietf-inet-types:ipv4-prefix
     +--rw multicast?     boolean
     +--rw link-detect?   boolean
     +--rw shutdown?      boolean
     +--rw bandwidth?     uint32
     +--ro state
        +--ro up-count?      uint16
        +--ro down-count?    uint16
        +--ro zif-type?      identityref
        +--ro ptm-status?    string <disabled>
        +--ro vlan-id?       uint16
        +--ro vni-id?        vni-id-type
        +--ro remote-vtep?   ietf-inet-types:ipv4-address
