Details

Previously permissions to read/write internal config storage spaces were
required:

- permissions: [read, write]
  spaces:
    - config_storage
    - config_storage_meta

Now, the config.storage.* API functions have access to these spaces
without an explicit permissions configuration. These permissions can be
removed from the configuration.

This change is planned for inclusion into 3.5.0, 3.4.1, 3.3.3, 3.2.2
releases.
