Add gratuitous-arp-accepted and unsolicited-na-accepted

[cagdasalagoz-arista]

Change Scope

Two new boolean leaf values will be added to paths below,

• interfaces/interface/subinterfaces/subinterface/ipv4/config/
• interfaces/interface/subinterfaces/subinterface/ipv6/config/.

A. Yang tree for IPv4

/oc-if:interfaces/oc-if:interface/oc-if:subinterfaces/oc-if:subinterface:
    +--rw ipv4
       +--rw config
       |  +--rw enabled?                     boolean
       |  +--rw mtu?                         uint16
       |  +--rw dhcp-client?                 boolean
       |  +--rw gratuitous-arp-accepted?     boolean       <<<new
       +--ro state
          +--ro enabled?                     boolean
          +--ro mtu?                         uint16
          +--ro dhcp-client?                 boolean
          +--ro gratuitous-arp-accepted?     boolean       <<<new
          +--ro counters

B. Yang tree for IPv6

/oc-if:interfaces/oc-if:interface/oc-if:subinterfaces/oc-if:subinterface:
    +--rw ipv6
       +--rw config
       |  +--rw enabled?                     boolean
       |  +--rw mtu?                         uint32
       |  +--rw dup-addr-detect-transmits?   uint32
       |  +--rw dhcp-client?                 boolean
       |  +--rw unsolicited-na-accepted?     boolean    <<<new
       +--ro state
          +--ro enabled?                     boolean
          +--ro mtu?                         uint32
          +--ro dup-addr-detect-transmits?   uint32
          +--ro dhcp-client?                 boolean
          +--ro unsolicited-na-accepted?     boolean    <<<new
          +--ro counters

As the name suggests these will be used to toggle if the device will accept (and process) or reject the gratuitous arp updates.

This change is backwards compatible

This looks good to me. Small comment on updating the versioning and I think this is ready to go.
