t1792: correct SSL parameter in Private Registry manifest
t1975: Add workaround for Tastypie create_api_key ImportError
t1984: Update deprecated import (django.conf.urls.defaults -> django.conf.urls)
t1818: Add a simple CoreID Registry

Support basic OMS CoreID and Personas in an OMS Registry.
Note that this code/commit originated with Maurycy, and is now
being separated out from the original commit in an effort to
isolate this addition of a simple CoreID Registry (from which
other commits can build off of).

The original commit been edited in the following ways:

* removed updates to the Private Registry manifest
* removed use of the (new) coreid_to_personas module (this will
  come in a separate commit).
* removed coreid_to_personas entry in the coreid fixture
* cleaned up a few imports
* added module-level doc snipppets
* separated API Resource registration from django's URL Route definitions
* removed PRIVATE_REGISTRY key in settings_snippet in CoreID Registry manifest
* disabled tests, at least until t1970 has been merged to qa-develop
t1953: add a utility to import any importable python object
t1927: add a manifest and module for Core ID Registration

This is a module which defines the generic structure for CoreID registration.
Details such as which classes to use for the RegistrationForm or View, have
been abstracted out and defined in constance. In other words, this app acts as
a wrapper around django-registration, creating an OMS App which can use any
Registration Form and View classes that can be imported. This makes it very
easy to make custom registration apps for different use-cases.

The included CoreIDRegistrationForm and CoreIDLocalRegistrationView sets up a
flow through requesting a First/Last name, Username, Email, and Password from
the user, and creates a CoreID (as a database entry and django user), before
sending the user to a confirmation/completion page.
t1951: map core IDs to personas in CoreID Registry
t1970: Create a FACT-enabled PersonaAuthorization class

This is primarily for APIs built with django and tastypie (but could be made
reusable). The objects allowed to be processed through each API Resource are
filtered through a FACT transformation function that allows only those
objects owned by the persona associated with the Token provided with the
request.
t1940: Filter the CoreID Registry's Persona APIs through FACT

Use the new FACT-enabled PersonaAuthorization to transform (filter) the Persona
APIs in the CoreID Registry.

The list of objects included in the response is based on the persona associated
with the Token provided with the request. The same can be said for the other
request methods to create/delete/update new and existing Personas and their
Attributes.
t2009: Use single quotes in triple-quoted docstrings
t2026: Use introspection endpoint for OIDC validation
t2027: Remove OpenIdConnectAuthorization.is_authorized() method
t2037: Add docs and tests to core ID- and persona-related modules
t2038: Remove extra space character from license
t2039: Rename cn_sandbox to funf_connector
t2040: Rename pds_sandbox to gps_demo_pds
t2041: Rename prox_sandbox to gps_demo_proximity
t2049: Namespace OIDC-related template variables in manifests
t1792: disable debugger by default, in Private Registry manifest
t1209: update manifests.json with the latest from the YAML files

but without dynamic values (no jinja template variables)
note that we're not deploying TABs through the Registry at this time, so this
update is also a bit moot.
