NP-1102: Support for Ansible playbook for offline migration (#61752)

This commit runs migration to change CNI from OpenShiftSDN to OVNKubernetes using ipi-aws-ovn workflow.

It also runs rollback to change CNI from OVNKubernetes to OpenShiftSDN using ipi-aws-sdn worflow.

This commit also creates a new workflow called ipi-aws-sdn to test the rollback.

OWNERS and OWNERS_ALIASES file has been added in config and jobs folder present under ci-operator folder for merge process of the PR.
