Here we add the context module from Neutron, although it is currently marked as private because it will undergo changes related to the ongoing enginefacade and Keystone V3 work. We also add some of the roles management methods from Neutron's policy module. These are required for the initial DB patches that follow this one. Partially implements: Blueprint neutron-lib Change-Id: I77f8a05d6e3167f3096ad637d124e47ac39a83df
