On Py27, the yaml module implementation uses a normal dictionary for implementation, resulting in arbitrary order for the parsed yaml. If the config option cloud_config_plugins is not set or empty, fallback to the default order defined in the factory. Config option `cloud_config_plugins` is now used for filtering the cloud config plugins to be executed, which was the original intended behaviour. Change-Id: I59ea56e473ab343a826ff8c38787cb7f11cebd27
