Description of problem: Answer to https://<node>:8443/api/host request has changed, and the ceph_version field for every service is empty. This doesn't allow client applications recognize to which Ceph version are connecting Version-Release number of selected component (if applicable): Returns empty value on 17.2.6-246.el9cp / 6.1.8 Returns empty value on 18.2.1-229.el9cp / 7.1.1 Returns empty value on 19.2.0-55.el9cp / 8.0.1 Returns the expected value on 16.2.10-248.el8cp / 5.3.6 How reproducible: Send a GET request for https://<node>:8443/api/host Steps to Reproduce: Note: in this example localhost is the MGR node 1 - Create a valid token by a api/auth request # curl -k -X POST "https://localhost:8443/api/auth" -H "Accept: application/vnd.ceph.api.v1.0+json" -H "Content-Type: application/json" -d '{"username": "admin_user", "password": "admin_password"}' 2 - Use the "token" field to create a GET request for api/host #curl -k -H "Accept: application/vnd.ceph.api.v1.0+json" -H "Authorization: Bearer <value_of_the_token_field>" -X GET 'https://localhost:8443/api/host' Actual results: Every "ceph_version" field for each service is empty [{"ceph_version": "", "services": [], "sources": {"ceph": false, "orchestrator": true}, "hostname": "mgmt-0.lab.upshift.rdu2.redhat.com", "addr": "10.0.94.184",
