Support for hypervisor generic 'virtual_host_uuid' fact

Add support for the recently added system profile fact virtual_host_uuid (https://github.com/RedHatInsights/inventory-schemas/pull/121) which replaces legacy facts
rhsm.VM_HOST_UUID and satellite.virtual_host_uuid We actually still need to consult the 'satellite'->'virtual_host_uuid' fact, because the reporting pipeline for Satellite doesn't yet use the canonical field (more info in https://github.com/RedHatInsights/yuptoo doesn't have any special handling of virtual_host_uuid, and the satellite plugin reports virtual_host_uuid as a Satellite-specific fact).

satellite.virtual_host_uuid references

• InventoryRepository
• InventoryHost

VM_HOST_UUID references

• insert-mock-hosts script [1]
• conduit api spec [2]
• ConsumerInventory
• InventoryHost
• InventoryRepository
• InventoryService

Done Criteria

• Conduit is reporting virtual_host_uuid
• Tally is consuming virtual_host_uuid instead of rhsm.VM_HOST_UUID
• IQE Note- Ephemeral environment tests are updated to use the virtual_host_uuid fact.
