Controller-runtime cache doesn't support field selectors, causing
incorrect filtering when using kubectl with field selectors like
--field-selector=metadata.namespace=tenant-kvaps or metadata.name=test.
Changes:
- Created pkg/registry/fields package with ParseFieldSelector utility
- Refactored field selector parsing logic in application, tenantmodule,
and tenantsecret registries to use common implementation
- Implemented manual filtering for metadata.name and metadata.namespace
in List() and Watch() methods
- Removed Raw field usage and field selectors from client.ListOptions
- Label selectors passed directly via LabelSelector field
Field selectors now properly filter resources by name and namespace
through manual post-processing after label-based filtering.
