Allows entities handled by the entity provider which implements this interface to have meta properties
attached to them, these properties can be accessed via the
EntityBroker, properties will be
stored and retrieved via the methods which are implemented in this interface
For our usage, meta properties are extra or additional properties that are attached to an entity
at runtime but are persisted so they can be retrieved later
Allows the entity provider to define and control the way properties are stored on its own entities,
if you would prefer to use the internal storage and only have lightweight property storage needs
then use
Propertyable instead
NOTE: the validity of references and parameters is checked in the broker before the call
goes to the provider
This is one of the capability extensions for the
EntityProvider interface
