[MCLAG] Portsorch don't handle "traffic_disable" in APP DB LAG table

[chenkelly]

trafficstars

According https://github.com/Azure/SONiC/pull/596, MCLAG_Enhancements_HLD.md#3222-app_lag_table

;Add one new attribute to existing LAG_TABLE to control whether traffic collection and distribution should be disabled for all LAG member ports. traffic_disable = "true"/"false" ;default is false

Producer is MclagSyncd Consumer, but portsorch don't handle this field in doLagTask (https://github.com/Azure/sonic-swss/pull/1331) https://github.com/Azure/sonic-swss/blob/master/orchagent/portsorch.cpp#L3580 Should we support this traffic distribution mode for LAG?
