Remove old library dependency - urlparse2
urlparse2 is an unmaintained library - last commit is 6 years old.
The library is not python3 compatible (at least it's dependecy - recordtype library).

HP's fork of python-redfish-library dropped urlparse2 last year...
https://github.com/HewlettPackard/python-ilorest-library/issues/28

Please, remove this dependency and use built-in functions to parse URL.
Thanks.
