  - Merge "Add specification for migrating Watcher to OpenStackSDK"
  - Add specification for migrating Watcher to OpenStackSDK

    This specification proposes a phased migration from individual
    Python client libraries to OpenStackSDK for inter-service
    communication. The individual client libraries (python-novaclient,
    python-cinderclient, etc.) are deprecated and scheduled for
    removal from future OpenStack releases.

    Phase 1 (2026.1) focuses on:
    - Establishing OpenStackSDK infrastructure
    - Migrating Nova client to SDK compute proxy
    - Creating migration patterns for subsequent phases

    Future phases will migrate remaining clients (Cinder, Keystone,
    Placement, Ironic) and eventually integrate Watcher itself into
    OpenStackSDK as an infra_optim service.
