Cannot access conductor-server with URL based creds

[marcocrasso]

Prior Python client for Conductor server works with requests, which parses creds from URLs if any, and makes an authentification header. This is useful for intranet servers.

How to reproduce

configuration = Configuration()
        self.assertEqual(
            configuration.host,
            'http://user:pass@your_secured_server:8080/api/'
        )

Trying to reach any resource of the above configured server will get a 401 error.
