Madhu Venugopal b219698e75 Add a GetAll function that returns only managed plugins supported by V2
The current GetAll handles both V2 and legacy plugins. Also due to the
nature of V1 plugins, it also loads them. This causes problems when
loading is not required. Hence adding an independent API that will
return only the plugins that are loaded using v2 mangaed plugins.
