Defines a Plugin annotation object.

Annotations in plugin classes can use this class in order to pass various metadata about the plugin through the parser to DiscoveryInterface::getDefinitions() calls. This allows the metadata of a class to be located with the class itself, rather than in module-based info hooks.
