Courseware base url should be taken from site configuration

[zahid-arbisoft]

I came across a situation where I had two different sites for LMS. The URL for courseware was generating wrong for one site due to following edx-platform code

        jump_to_courseware_url = reverse(
            'jump_to',
            kwargs={
                'course_id': str(block_key.course_key),
                'location': str(block_key),
            },
            request=self.context['request'],
        )

In code, mostly edx is using configuration_helpers to get env variables. Is it possible to get the base URL using configuration_helpers for courseware URLs, and also for the bookmark, resume course button, etc
