    Do not depend on python-openstackclient

    OpenStack client is not a runtime dependency of ironicclient,
    and having it in requirements just brings in many dependencies
    which might not be needed at all when using the Python API of the client
    only (for example in server-side applications).

    Although dependency on osc-lib is enough for unit tests, add
    python-openstackclient to test-requirements so that functional tests
    pass.

    Also, add a setuptools 'extra' so that users can install
    python-openstackclient together with ironicclient if wishing to do so
    as follows:

        pip install python-ironicclient[cli]
