 * Introduces a new {@link CoordinatorPlugin} interface for native C++ clusters.
 * Certain elements of the {@link Plugin} SPI are not used in Prestissimo deployments, or may result in inconsistencies.
 * The {@link CoordinatorPlugin} includes only the interfaces relevant to native C++ clusters and
 * is a successor to {@link Plugin} and will eventually replace it.
 * It contains only interfaces that are valid and used in a coordinator.
