Implement a new automated test to cover this behaviour.

Proposed test steps:

            1. Install subscription-manager, rhc, rhc-worker-script, insights-client
            2. Create an inhibitor in the machine
            3. Create a TOML file with the envvar to skip the previous inhibitor.
            4. Run rhc connect with given credentials to subscribe
               the machine and register to insights
            5. Check that the host is visible as CentOS in the UI
            6. Run the pre-conversion analysis task in the machine
            7. Verify that one inhibitor was raised but skipped due the envvar
            8. Run the pre-conversion analysis task
            9. Verify the conversion finished successfully
