* Authentication mechanism
*
* An authentication mechanism can have services injected during construction,
* such as \OCP\IDB for database operations. This allows an authentication
* mechanism to perform advanced operations based on provided information.
*
* An authenication scheme defines the parameter interface, common to the
* storage implementation, the backend and the authentication mechanism.
* A storage implementation expects parameters according to the authentication
* scheme, which are provided from the authentication mechanism.
*
* This class uses the following traits:
* - VisibilityTrait
* Restrict usage to admin-only/none
* - FrontendDefinitionTrait
* Specify configuration parameters and other definitions
* - StorageModifierTrait
* Object can affect storage mounting
