Standardize https driver errors on consistent detailed response

[sfc-gh-afedorov]

Right now, the different errors that can come out of the HTTPS driver are not consistent in the keys they return, nor do they have a lot of details to help someone debug, forcing them in some cases to use curl side-by-side when the EF could just return more helpful details, instead.

The HTTPError was fixed in a soon-to-be-discarded branch here by changing that except block to —

        except HTTPError as e:
            content_type = e.headers.get('Content-Type')
            response_body = e.read().decode()
            result = {
                'error': 'HTTPError',
                'url': next_url,
                'status': e.status,
                'reason': e.reason,
                'body': (
                    loads(response_body)
                    if content_type.startswith('application/json')
                    else response_body
                ),
            }

We want to migrate that code and also standardize the other errors on having a subset of keys {"error", "url", "status", "reason", "body"}.
