ceilometer client is not created properly

When heat and ceilometer are configured for https, heat fails to communicate to ceilometer .

This happens because the ceilometer client is not created properly. heat should use get_client to create client object instead of directly calling Client function. https://github.com/openstack/python-ceilometerclient/blob/master/ceilometerclient/client.py#L278
This is required because get_client function sets the verify parameter correctly before making the client connection. There was a bug in ceilometer client earlier which is now fixed. https://review.openstack.org/#/c/146951

    Fix heat and ceilometer client connection

    Heat Ceilometer client plugin uses direclty the Client function of
    python-ceilometerclient which does not exposes all the parameters
    required to make a https connection with ceilometer. Instead of
    this get_client fucntion of ceilometer client should be used which
    set all the ssl parameters correctly
