37b9e6d1ea An interface that allows pre-filter plugins to update their pre-calculated. 
This is needed to allow efficient preemption simulations: during preemption, we remove/add pods from each node before running the filter plugins again to evaluate whether removing/adding specific pods will allow the incoming pod to be scheduled on the node. Instead of calling prefilter again, we should allow the plugin to do incremental update to its pre-computed state.

89f936f6ac Modified the Filter interface to pass in nodeinfo instead of node name. 
This is necessary to support preemption, which relies on passing modified nodeinfo objects to the filters to simulate evicting lower-priority pods.

cannot be written without lock.

f58abdf966 Use scheduler cache in affinity priority functions 
Make the cache implement NodeLister and expose it to the priority
functions. This way, the priority functions make use of a single cache,
the scheduler's, instead of mixing it with the lister's caches.
