Review comment:
a simple MiniClusterResource would be sufficient in this test, and probably
others as well. I think it makes sense to do this as part of the separation.

> Start MiniCluster with random REST port
> ---------------------------------------
>
> Key: FLINK-10637
> URL: https://issues.apache.org/jira/browse/FLINK-10637
> Project: Flink
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 1.5.4, 1.6.1, 1.7.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.5.6, 1.6.3, 1.7.0
>
>
> 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.
