Add Barbican HSM custom image support

- Add new Makefile variables for HSM-enabled Barbican deployments:
  BARBICAN_API_IMAGE, BARBICAN_WORKER_IMAGE, BARBICAN_HSM_ENABLED
- Add conditional logic to use custom images when HSM is enabled
- Update barbican_deploy_prep target to handle custom image deployment
- Add HSM backend selection in standalone openstack.sh script
- Support PKCS#11 backend when BARBICAN_HSM_ENABLED=true
