Replace raw keystoneauth1 HTTP calls with the OpenStackSDK
placement proxy. This aligns PlacementHelper with the SDK-based
approach used elsewhere in Watcher.
Key changes:
- Use connection.placement.resource_provider_inventories()
instead of raw GET requests
- Rename from_placement_api to from_openstacksdk to match
the wrapper pattern in nova_helper
- Use BaseConnectionMixin to provide the sdk connection
- Remove unused osc parameter from PlacementHelper
- Add [placement] config group with keystoneauth options
- Deprecate [placement_client] options in favor of [placement]
- Update PlacementResourcesMixin to return real OpenStackSDK
ResourceProviderInventory objects
- Rewrite tests to mock the SDK connection
