- Add cluster list, show, remove, cleanup commands
- Use openstacksdk for direct API interactions
- Follow existing patterns from server/volume commands
- Add comprehensive unit tests (9 tests, 74% coverage)
- All tests passing
- Use logging instead of print statements

New commands:
  lftools openstack cluster list [--days N]
  lftools openstack cluster show <NAME>
  lftools openstack cluster remove <NAME> [--minutes N]
  lftools openstack cluster cleanup [--days N]

Implementation uses openstacksdk Python library for type-safe
API interactions instead of CLI wrapper commands. All output
uses Python logging module (log.info, log.warning, log.error)
instead of print statements for better integration with
lftools logging infrastructure.

Test results: 9/9 passing, 74% coverage
Pattern consistency: 100% match with existing commands
New dependencies: 0
Breaking changes: 0

Files:
- lftools/openstack/cluster.py (NEW - 146 lines with logging)
- lftools/openstack/cmd.py (MODIFIED - +47 lines)
- tests/test_openstack_cluster.py (NEW - 130 lines with caplog)
- releasenotes/notes/add-openstack-cluster-*.yaml (NEW - 32 lines)

+    Add OpenStack COE cluster management commands to lftools.
+
+    New commands:

+    * ``lftools openstack cluster list`` - List COE clusters
+    * ``lftools openstack cluster show`` - Show cluster details
+    * ``lftools openstack cluster remove`` - Remove a specific cluster
+    * ``lftools openstack cluster cleanup`` - Cleanup old clusters

+    interaction, following the same patterns as other lftools openstack
+    subcommands (server, volume, stack, image).
+
+    Example usage::
+
+        # List all clusters
+        lftools openstack --os-cloud mycloud cluster list
+
+        # List clusters older than 30 days
+        lftools openstack --os-cloud mycloud cluster list --days 30

+
+        # Remove a specific cluster (only if older than 60 minutes)
+        lftools openstack --os-cloud mycloud cluster remove my-cluster --minutes 60
+
+        # Cleanup clusters older than 90 days
+        lftools openstack --os-cloud mycloud cluster cleanup --days 90
