Subject: [PATCH] [FLINK-4030] Revert Surefire version to 2.18.1

The ScalaShellITCase sometimes gets stuck before test execution with no output
in the logs. We ran about a hundred builds against Surefire 2.18.1 which
confirmed that the failures don't occur with this version.

Waiting for an upstream fix until this can be reverted.
