Description

The MiniCluster picks a random port for the RpcService but not for the REST server endpoint. Due to this it falls back to 8081. This can lead to port conflicts if tests are executed concurrently.

I propose to rename the MiniClusterResource into MiniClusterResourceWithRestClient and add a new MiniClusterResource which only starts a MiniCluster with the REST port set to 0.
