Changes to the baseclass for datasources so strategies can be made compatible with every datasource. Baseclass methods clearly describe expected values and types for both parameters and for method returns. query_retry has been added as base method since every current datasource implements it. Ceilometer is updated to work with the new baseclass. Several methods which are not part of the baseclass and are not used by any strategies are removed. The signature of these methods would have to be changed to fit with the new base class while it would limit strategies to only work with Ceilometer. Gnocchi is updated to work with the new baseclass. Gnocchi and Ceilometer will perform a transformation for the host_airflow metric as it retrieves 1/10 th of the actual CFM Monasca is updated to work with the new baseclass. FakeMetrics for Gnocchi, Monasca and Ceilometer are updated to work with the new method signatures of the baseclass. FakeClusterAndMetrics for Ceilometer and Gnocchi are updated to work with the new method signatures of the baseclass. The strategies workload_balance, vm_workload_consolidation, workload_stabilization, basic_consolidation, noisy_neighbour, outlet_temp_control and uniform_airflow are updated to work with the new datasource baseclass. This patch will break compatibility with plugin strategies and datasources due to the changes in signatures.
