do not list openstackclient as a requirement

[Steve Martinelli]

python-openstackclient is listed as a requirement (https://github.com/openstack/python-manilaclient/blob/master/requirements.txt#L21). But AFACT, the OSC plugin (https://github.com/openstack/python-manilaclient/blob/bd28eda9d21eab043ac85c78f620f131f4b156b4/manilaclient/client.py#L20) is incomplete as there are no entry_points listed in setup.cfg (https://github.com/openstack/python-manilaclient/blob/master/setup.cfg).

It seems like it was mostly lifted for use in functional tests: https://github.com/openstack/python-manilaclient/blob/0a4ccec3f5357a5ef0526553d8eaced31691f8d4/manilaclient/tests/functional/client.py#L158-L161

It seems like manilaclient is still using the old nova/argparse method (https://github.com/openstack/python-manilaclient/blob/0a4ccec3f5357a5ef0526553d8eaced31691f8d4/manilaclient/shell.py#L106-L114) - not sure if you all plan on moving to an openstackclient plugin, but you might want to put openstackclient in test-requirements.txt if it's not going to be used.
