Flink load tests fail: NoClassDefFoundError: MessageBodyReader

Note that this is not showing up in the cron versions of the load tests right now because we disabled the tests from actually running due to BEAM-12898.

16:52:03 ERROR: (gcloud.dataproc.clusters.create) Operation [projects/apache-beam-testing/regions/global/operations/44dc1572-011e-3faf-87e7-a09ccb26be14] failed: Initialization action failed. Failed action 'gs://beam-flink-cluster/init-actions/flink.sh', see output in: gs://dataproc-6c5fbcbb-a2de-406e-9cf7-8c1ce0b6a604-us/google-cloud-dataproc-metainfo/06c4cc6f-776e-424e-878b-2abe6b5200ed/beam-loadtests-python-pardo-flink-batch-28-m/dataproc-initialization-script-2_output.

The log file linked contains the exception below. It is the same as the exception in FLINK-12493 so we can probably fix it by setting HADOOP_CLASSPATH.
