The quantum/api/v2/views.py module is replaced by is_visible properties in the RESOURCE_ATTRIBUTE_MAP defined in quantum/api/v2/attributes.py. Extensions are given the ability to add extended attribute descriptions to this map during initialization, allowing extended attributes to be implemented similarly to core attributes in plugins. Resolves bug 1023111. Change-Id: Ic6e224d5d841b6a1d4d1c762d7306adaf91f7a2d
