Description

All valuable test utils are only found in test-jars, but should be found in the compile scope of the test util projects.

• TestLogger
• RetryRules
• MiniClusters
• TestEnvironments
• ...

Additionally, we have dependencies where the compile scope of some projects depends on test-jars of other projects. That can create problems in some builds and with some tools.

Here is how we can fix that:

• Create a flink-testutils-core project, which has the test utils currently contained in the flink-core test-jar in the main scope. That means the flink-core test-jar is not needed by other projects any more.
• Make the Mini Cluster available in flink-test-utils main scope.
• To remove the test-jar dependency on flink-runtime from the flink-test-utils project, we need to move the test actor classes to the main scope in flink-runtime.

This is related to FLINK-1827 (a followup).
