[6.15.z] Fix content_facet_attributes attributes

[Satellite-QE]

Cherrypick of PR: #14224

i.e.
['content_view_id'] is now a separate dict
['content_view']['id']

Problem Statement

tests/foreman/api/test_host.py::test_positive_create_and_update_with_content_view
tests/foreman/api/test_host.py::test_positive_create_inherit_lce_cv

tests are failing for foreman 3.9 (6.15.z) because *_id keys are not found

Solution

access id as key from parent dict
