We could map those in ExceptionMapper from pr#820. Seems a little overkill, but I suppose that is why it is there.

(ie, remove the code from python-rhsm that raises those exceptions with a msg=
then add those exception types to ExceptionMapper, and the corresponding strings. Then python-rhsm
would just raise for ex, ServerUrlParseErrorScheme, and ExceptionMapper would know the translated string for it)
