Boden R d63032b547 use APIExtensionDescriptor for plugins with defs in lib
A few plugins that have API defs in neutron-lib still inherit from
ExtensionDescriptor and thus return their def's values. This patch
changes them to inherit from APIExtensionDescriptor which handles
returning these values for you.

In addition neutron-lib's APIDefinitionFixture is used in the
AttributeMapMemento to ensure API def maps are handled accordingly.
