[RFE] virt-who need to make sure there is only one entry in satellite content host for the same hypervisor when configure hypervisor_id for uuid or hostname or hwuuid
For candlepin, overall changes necessary are:
1) Accept all 3 (hw_uuid, uuid, hostname) [TBD: as facts or as their own thing]
2) When receiving a hypervisor checkin, lookup existing hypervisors by the tuple (hw_uuid, uuid, hostname) & delete/migrate as necessary.
Some design decisions to be made before implementation.
