HA_Chassis_Group TABLE
Table representing a group of chassis which can provide High
availability services. Each chassis in the group is represented
by the table HA_Chassis. The HA chassis with highest priority

over the responsibility of providing the HA. If ha_chassis_group

HA chassis group provides the gateway functionality and redirects
the gateway traffic to the master of this group.
