------------------
OAuth2.0 Provider - Bugfixes

* 753: Fix acceptance of valid IPv6 addresses in URI validation

OAuth2.0 Client - Bugfixes

* 730: Base OAuth2 Client now has a consistent way of managing the `scope`: it consistently
 relies on the `scope` provided in the constructor if any, except if overridden temporarily
 in a method call. Note that in particular providing a non-None `scope` in
 `prepare_authorization_request` or `prepare_refresh_token` does not override anymore
 `self.scope` forever, it is just used temporarily.
* 726: MobileApplicationClient.prepare_request_uri and MobileApplicationClient.parse_request_uri_response,
 ServiceApplicationClient.prepare_request_body,
 and WebApplicationClient.prepare_request_uri now correctly use the default `scope` provided in
 constructor.
* 725: LegacyApplicationClient.prepare_request_body now correctly uses the default `scope` provided in constructor

OAuth2.0 Provider - Bugfixes
* 711: client_credentials grant: fix log message
* 746: OpenID Connect Hybrid - fix nonce not passed to add_id_token
* 756: Different prompt values are now handled according to spec (e.g. prompt=none)
* 759: OpenID Connect - fix Authorization: Basic parsing

General
* 716: improved skeleton validator for public vs private client
* 720: replace mock library with standard unittest.mock
* 727: build isort integration
* 734: python2 code removal
