Tests of keystone action need oauthlib

[pengdake]

According to https://wiki.openstack.org/wiki/Testr#Debugging_.28pdb.29_Tests,
I run the test about mistral.tests.unit.actions.openstack.test_generator.GeneratorTest.test_generator.

I get two kinds error from stdout:

1. ERROR [mistral.actions.openstack.action_generator.base] Failed to create action: nova.hosts_find
Traceback (most recent call last):
  File "mistral/actions/openstack/action_generator/base.py", line 143, in create_actions
    client_method = class_.get_fake_client_method()
  File "mistral/actions/openstack/base.py", line 75, in get_fake_client_method
    return cls._get_client_method(cls._get_fake_client())
  File "mistral/actions/openstack/base.py", line 59, in _get_client_method
    attribute = getattr(attribute, attr)
AttributeError: 'Client' object has no attribute 'hosts'

2. ERROR [mistral.actions.openstack.action_generator.base] Failed to create action: keystone.oauth1.request_tokens_find
Traceback (most recent call last):
  File "mistral/actions/openstack/action_generator/base.py", line 143, in create_actions

    return cls._get_client_method(cls._get_fake_client())
  File "mistral/actions/openstack/base.py", line 59, in _get_client_method
    attribute = getattr(attribute, attr)
  File "/home/pengdake/work/openstack/mistral/.tox/py27/local/lib/python2.7/site-packages/keystoneclient/v3/contrib/oauth1/core.py", line 64, in __getattribute__
    _('To use %r oauthlib must be installed') % name)
NotImplementedError: To use 'request_tokens' oauthlib must be installed

I don't know why run test by tox successed, but the error exists indeed.
