Today we shim the RESOURCE_ATTRIBUTE_MAP in neutron; it references the
equivelant in neutron-lib named RESOURCES.
This patch removes neutron's RESOURCE_ATTRIBUTE_MAP and cleans up
neutron.api.v2.attributes in prep to delete it.
To do so:
- CORE_RESOURCES and RESOURCE_FOREIGN_KEYS are moved to the single
module that references them respectively and the are made private (no
consumers use them).
- get_collection_info is removed and instead the 2 uses in neutron
just use the get() method of the RESOURCES map. There are no external
uses of get_collection_info.
- References using RESOURCE_ATTRIBUTE_MAP are switched over to
neutron-lib's RESOURCES.
- The neutron.api.v2.attributes module is removed as it's empty now.
- A few api attribute UTs are removed; there's nothing to test as per
this patch.
