------------------------------------------------------------------------
Attaching a proof of concept patch (applied cleanly on top of YARN-7612) that
decouples Algorithm from constraints introducing canAssign method which
navigates thought placement constraints and just return if a placement in a
Node is feasible or not. Currently as part of the algorithm class (debatable).
Planning Algorithm should only add logic to the way we iterate through
SchedulingRequests and cluster Nodes and not how we satisfy the constraints -
this is the first step towards that goal
