Add Swift RGW configuration playbook for post-adoption setup

This commit adds support for configuring Swift object storage to use
Ceph RGW after adoption is complete. The configuration requires the
adopted OpenShift environment to be running with Keystone
services available.

Changes:
- Add configure_swift_rgw.yaml playbook with three phases:
  1. Extract Swift password and Keystone endpoint from OpenShift
  2. Configure Ceph RGW with Keystone integration settings
  3. Configure Swift endpoints to use RGW backend

- Add test-configure-object Makefile target to invoke the playbook

- Playbook uses variables extracted at runtime from the live OpenShift
  environment (ceph_keystone_ep, ceph_keystone_swift_pwd, and
  ceph_rgw_virtual_ips_list) which are passed to the ceph_migrate role
