Code Issues Proposed changes

External OAuth2.0 Authorization Server Support 

Added the ability to authenticate using a system-scoped token and the
ability to authenticate using a cached token to the
external_oauth2_token filter.

Implements: blueprint enhance-oauth2-interoperability

Configuration for external authorization
----------------------------------------
If an external authorization server is used from Keystonemiddleware, the
configuration file settings for the main application must be changed. The
system supports 5 authentication methods, tls_client_auth, client_secret_basic,
client_secret_post, client_secret_jwt, and private_key_jwt, which are specified
in auth_method. The required config depends on the authentication method.
The two config file modifications required when using an external authorization
server are described below.
.. NOTE::
Settings for accepting https requests and mTLS connections depend on each
OpenStack service that uses Keystonemiddleware.
Change to use the ext_oauth2_token filter instead of authtoken:
.. code-block:: ini
[pipeline:main]
pipeline = ext_oauth2_token myService
[filter:ext_oauth2_token]
paste.filter_factory = keystonemiddleware.external_oauth2_token:filter_factory
Add the config group for external authentication server:
.. code-block:: ini
[ext_oauth2_auth]
# Required if identity server requires client certificate.
#certfile = <None>
# Required if identity server requires client private key.
#keyfile = <None>
# A PEM encoded Certificate Authority to use when verifying HTTPs
# connections. Defaults to system CAs.

# Endpoint. The Authorization Server will verify that it is an intended
# audience for the token.

# otherwise the value is ignored.

# If the access token generated by the Authorization Server is bound to the
# OAuth 2.0 certificate thumbprint, the value can be set to true, and then
# the keystone middleware will verify the thumbprint.

# registered with the Authorization Server. When the auth_method is

# The jwt_algorithm must use the algorithm specified by the Authorization

[`blueprint enhance-oauth2-interoperability <https://blueprints.launchpad.net/keystone/+spec/enhance-oauth2-interoperability>`_]
Added the ability to authenticate using a system-scoped token and the
ability to authenticate using a cached token to the external_oauth2_token
filter.
