remote partitioning doesn't work if you're using graalvm

[joshlong]

i have an example, here that fails if you don't add a few extra hints for a simple example compiled to graalvm and using remote partitioning. please add the following hints to the jar itself so users don't need to

i had to put this on the worker node and @ImportRuntimeHints it:

    static class Hints implements RuntimeHintsRegistrar {

        @Override
        public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
            var mcs = MemberCategory.values();
            hints.reflection().registerType(StepExecutionRequestHandler.class, mcs);
            hints.serialization().registerType(StepExecutionRequest.class);
        }
    }

i had to put this on the leader node and @ImportRuntimeHints it:

    static class Hints implements RuntimeHintsRegistrar {

        @Override
        public void registerHints(RuntimeHints hints, ClassLoader classLoader) {

            var mcs = MemberCategory.values();
            hints.reflection().registerType(MessageChannelPartitionHandler.class, mcs);
            hints.serialization().registerType(StepExecutionRequest.class);
        }
    }

I was watching the tips video https://www.youtube.com/watch?v=dmdkJ3ZmT5E&list=PLgGXSWYM2FpPw8rV0tZoMiJYSCiLhPnOc&index=28 good to see that now the hint seem to be added.
