Normal Description of problem:
When there is HW model created and a host is created with the associated HW model and you then try to delete this HW model via UI, deletion fails (as it should), but there is also just an error message containing
"Request failed with status code 422"
there should be this error message,
"HW_MODEL_NAME is used by HOST.COM"
which can also be seen in the production log below.

How reproducible:
100%
Is this issue a regression from an earlier version:
No
Steps to Reproduce:
1. Create HW model
2. Create host associated with the HW model
3. Try to delete HW model
4. Observe UI error message
Actual behavior:
Deletion of the associated HW model fails with a plain 422 error in the Satellite UI
Expected behavior:
Deletion of the associated HW model fails with a more descriptive error in the Satellite UI.
Something like Cannot delete HW_MODEL_NAME, it is used by HOST.COM
