#### Registering test clusters

When using the elasticsearch test cluster plugin we want to use (similar to the task avoidance API) a Gradle API to create domain objects lazy or only if required by the build.
Therefore we register test cluster by using the following syntax:

    def someClusterProvider = testClusters.register('someCluster') { ... }
