Adds existing solution to all raise_for_status calls.

Functional demonstration

Example:

requests.exceptions.HTTPError: ('500 Server Error: Internal Server Error for url: https://robo-main-orcharhino-alma8.infra.dev.atix/katello/api/v2/repositories/42', {'displayMessage': 'Repository cannot be deleted since it has already been included in a published Content View. Please delete all Content View versions containing this repository before attempting to delete it or use --remove-from-content-view-versions flag to automatically remove the repository from all published versions.', 'errors': ['Repository cannot be deleted since it has already been included in a published Content View. Please delete all Content View versions containing this repository before attempting to delete it or use --remove-from-content-view-versions flag to automatically remove the repository from all published versions.']})

vs.

requests.exceptions.HTTPError: 500 Server Error: Internal Server Error for url: https://robo-main-orcharhino-alma8.infra.dev.atix/katello/api/v2/repositories/24
