@tillrohrmann, There is not a generic way for both Yarn and Mesos, as their
resource allocation interface are different. I think the YARN/MESOS resource
manager should handle it in their own way. For example, in YarnResourceManager,
it can add all extended resources to the yarn Resource.class by call
setResourceValue(name, value). And then only if YARN support a new resource
type, user can define it without code changing in flink.
