openconfig-macsec model : We need a knob to enable or disable replay protection

[ishwarbnaik]

In openconfig-macsec model macsec-interfaces-interface-config grouping, We have replay-protection attribute which only allows configuring unsigned int value, and this value to be used for replay protection window in MACsec.

There is no option in openconfig-macsec to enable or disable replay-protection, effectively making it enabled always.

As per IEEE 802.1AE-2018 standard, replay protection enabled/disabled should have different impact on late pkts received and should update different counters in each case ( IEEE 802.1AE-2018 Figure 10-4 ).

So, we will need a new knob in macsec-interfaces-interface-config group to enable or disable the replay protection aswell.
