Description of problem:
Currently GET of hosts returns only owner_id and owner_type. As an API user i would like to have also the owner_name for presentation and easier verification. The missing owner_name is also inconsistent with almost all other fields that have a _name variant available

"owner_id": 1,
"owner_type": "User",
