function geturl will rasie a TypeError if we specify a str url and
replace the scheme value with a unicode value. In order to work with
both string redfish url and unicode redfish url, we need to convert
the "https" to the scheme's type.
This bug canbe reproduced with:
from __future__ import unicode_literals
from __future__ import print_function
from __future__ import division
from __future__ import absolute_import
from future import standard_library
standard_library.install_aliases()
from builtins import object
import json
from urllib.parse import urlparse, urljoin, urlunparse
url=urlparse(unicode("http://127.0.0.1"))
url._replace(scheme="https").geturl()
url=urlparse(str("http://127.0.0.1"))
url._replace(scheme="https").geturl()
