I have put it inside loop so that node reports get updated periodically.
This helps in keeping latest available resources in node reports so that on
container kill/restart, we can allocate nodes based on latest available
resources.
> Enable non-affinity of operators per node (not containers)

> The issue happens on cloud which provides virtual cores with software like
> Xen underneath. In effect if CPU intensive operators land up on same node we
> have a resource bottleneck,
> Need to create an attribute that does the following
> - Operators A & B should not be on same node
> - Stram should use this attribute to try to get containers on different node
> It is understood that the user is making an explicit choice to use NIC
> instead of stream local optimization
