We need to build:

• a table (migration)
• a task to read data from the engine and put it into the table
• a facet to track the host id (already exists in rh_cloud)

We also need to make sure the hosts IDs are synchronized and the UUID exists in the insights_facet.

Currently there is a task that is responsible for it: https://github.com/theforeman/foreman_rh_cloud/blob/develop/lib/inventory_sync/async/inventory_hosts_sync.rb
