Add test-operator KUTTL integration

Add test-operator to install_yamls following the standard operator
pattern (manila, horizon, cinder, etc).

Provides:
- Operator deployment: test_prep, test, test_cleanup
- CR deployment: test_deploy_prep, test_deploy_cleanup
- KUTTL tests: test_kuttl, test_kuttl_run

Usage: make test_kuttl
