When installing MTC 1.7.19 from OperatorHub, the migration-operator pod fails during startup. The logs indicate that the Ansible Runner is crashing due to an unhandled KeyError: 'http+unix'. As a result, the installation is stuck in an incomplete state and required controller pods are never deployed. This renders the operator non-functional.

The issue appears to be related to how ansible_runner_http handles status callbacks involving the http+unix scheme, which is not recognized by urllib3 and lacks a corresponding handler in key_fn_by_scheme.

Steps to Reproduce:

1. Navigate to OperatorHub in the OpenShift console.

1. Attempt to install MTC 1.7.19

1. If pre-installed, monitor the status of the MTC installation using:
   $oc get all -n openshift-migration
    

Actual results:

• migration-operator pod crashes in a loop.

• Operator installation remains incomplete and non-functional.

• From the migration operator logs:
