> We want to be able to have topologies of older version (for example 0.10) to
> run on 2.x cluster. User might submit topologies with 0.10 configs which
> includes "backtype.storm". It will fail the validation process on the nimbus
> because the "backtype.storm.XXX" class not found. For now it's really just
> about TOPOLOGY_SCHEDULER_STRATEGY config. We might want to loosen the
> constraints for @isImplementationOfClass so that if "backtype.storm.XXX" is
> not found, we try with "org.apache.storm.XXX and if it passed, we let it pass
> the validation.
