This whole thing is a mess. examples is doing the right thing and using get_extra_config, but its docs are wrong. functional is reading config from a non-standard place but is the place that the examples docs incorrect say it should be read from. Update both places to read from the RIGHT location and update the docs as well. Make examples support setting a key to use and then set that key in tox so that we can just use the functional settings for both. Also, fix the clustering functional test so that it consumes the IMAGE_NAME discovered in functional.base. Change-Id: Ia9f150bbdd3825cb3e0d4282af3ca8f23dc1d888
