> slider has an anti-affinity flag in roles (visible in resources.json?), which 
> is ignored.
> YARN-1042 promises this for YARN, slider will need
> # flag in resources.json
> # use in container requests
> we may also want two policies: anti-affinity-desired, and -required. Then if 
> required nodes get >1 container for the same component type on the same node, 
> it'd have to request a new one and return the old one (Risk: getting the same 
> one back).
