Python 3: AttributeError in find_resource

[Cyril Roelandt]

When running tests from keystoneclient/tests/test_utils.py with Python 3, the following error occurs:

======================================================================
ERROR: keystoneclient.tests.test_utils.FindResourceTestCase.test_find_by_str_name
----------------------------------------------------------------------
testtools.testresult.real._StringException: Traceback (most recent call last):
  File "/home/cyril/openstack/python-keystoneclient/keystoneclient/tests/test_utils.py", line 87, in test_find_by_str_name
    output = utils.find_resource(self.manager, 'entity_one')
  File "/home/cyril/openstack/python-keystoneclient/keystoneclient/utils.py", line 105, in find_resource
    name_or_id = name_or_id.decode('utf-8', 'strict')
AttributeError: 'str' object has no attribute 'decode'

name_or_id is probably a text string in Python, and therefore it cannot be decoded.

    Do not try to call decode() on a text string

    This fixes a call to 'isinstance' that only worked on Python2.
