Better error messages needed when only 1 client worker deployed

DistributedWorkersEnsemble throws this arg error if there happens to be only one configured worker.

Swarm at least throws a useful error message telling you it requires more than 1 worker.

TF should also probably throw an error if clients is less than 2
