This enables submission of multiple jobs in the Jepsen tests. The job specifications are in an .edn file that must be passed as command line arguments. The checker verifies that all jobs are running at the end of the test. The job cancellation function now cancels all jobs at once. Delete script/run-tests.sh and move code to docker/run-tests.sh.
This enables toggling the setup of test dependencies, such as Hadooop, Mesos, and, ZooKeeper through the --test-spec edn file. The type of the Flink cluster can also be specified via: :flink-yarn-job :flink-yarn-session :flink-mesos-session, and :flink-standalone-session. Retryable operations that exhausted all attempts, now propagate the exception by default. This is to fail fast if during the db/setup!, an operation, such as Flink job submission, fails to complete.

… tests should fail if exception isn't thrown This commit strengthens tests in StateBackendMigrationTestBase that depend on a certain state operation (restoring state, accessing state, etc.) to be failing to assert correct behaviour. However, we previously do not really fail the test if no exception was thrown when there should be. This also caught some bugs in the test itself which had the tests verifying incorrect behaviour.
…ackend should always be compatible Previously, we were only checking if the new namespace serializer is incompatible, while properly we should be checking that it is strictly compatible. This doesn't affect any user expected behaviour, since the namespace serializer is never exposed to users.
The traversal of the DAG is not efficient enough at some places which can lead to very long plan creation times. This introduces caching for the traversal to avoid traversing nodes multiple times. Caching is performed at two places: - when registering Kryo types - when determining the maximum parallelism

The test completes in 500ms on my machine. On Travis the resources are much more limited and it fails occasionally. The following should ensure the test does not fail anymore: - Increase test timeout to 30 seconds - Reduce complexity of tests by decreasing branching factor
