This patch is introducing new commands to ovsdbapp to work with the new
HA_Chassis_Group and HA_Chassis tables in OVN Northbound database.
These tables were introduced by the commit [0] in core OVN which created
a new type of port called "external" that can be used for various things
including but not limited to: SR-IOV and baremetal booting support.
