cifmw_ceph_client: Discover Ceph RGW and create Glance secrets

This patch enhances the cifmw_ceph_client role to:
- Automatically discover Ceph RGW (RADOS Gateway) endpoint and credentials
- Create Glance secrets using the discovered RGW settings

This integration allows Glance to leverage Ceph RGW for secret storage
when object store backends are enabled in the environment.

Changes:
- Add RGW discovery tasks to the role
- Add logic to create Glance secrets with RGW config
