Consumer lookup plugins now reach the merged config through the Ansible
lookup loader instead of importing get_merged_applications /
get_merged_domains from utils.cache. The merge stays one cached
implementation surfaced via the applications/config/domains/users lookups;
consumers call lookup_loader.get(...).run() (the compose_networks idiom).
- get_merged_applications walks the whole meta/ tree recursively
(meta/**/*.yml to applications.<app>.<path>, addons and any depth) and
folds the raw meta/volumes.yml subtree onto applications.<app>.volumes
after the templar render so the Jinja source: strings stay unrendered.
- 31 consumer lookups rerouted; providers (applications/config/
applications_current_play/users/domains) and the raw-volume accessors
(volume/nginx) keep the cache import behind # nocheck: lookup-cache-import.
- New lint test_no_cache_imports_in_lookups enforces the contract.
- nfs_flavor is now the flavor SPOT (svc-storage-nfs-server + nfs_client_src
resolve via lookup('nfs_flavor')); removed the unused STORAGE_NFS_FLAVOR
group_var. Extracted extract_default_credentials to
utils/cache/schema_credentials.py to keep applications.py under the cap.
