Today we have a number of extensions that must provide boilerplate/redundant code in their extension class to return basic API definition attributes such as name, description, alias, etc.. For example [1]. This patch proposes we can provide most of that boilerplate code right in a base extension descriptor class; just have extension sub-classes provide their API definition. With this patch, code such as [1] gets reduced to a class definition with a single class-level attribute to specify the API definition for the extension. For sample usage, have a look at [2] that used as a dummy patch to test PS4/PS7 of this change with neutron master.
