Improve performance of scheduling queue by adding a hash map to track all pods with a nominatedNodeName

**What this PR does / why we need it**:
Our investigations show that there is a performance regression in the new scheduling queue which is not enabled by default and is enabled only if "priority and preemption" which is an alpha feature is enabled. This PR is an important performance improvement for those who want to use priority and preemption in larger clusters.
The PR adds a hash table to track nominated Pods so that finding such Pods will be faster.
Other than improving performance, we don't expect this PR to change behavior of scheduler.

Revert "Change equivalence class hashing function" 2018-01-26 18:13:15 -08:00
Jonathan Basseri 466a499fcb Move equivalence class hash code.
This moves the equivalence hashing code from
algorithm/predicates/utils.go to core/equivalence_cache.go.

In the process, making the hashing function and hashing function factory
both injectable dependencies is removed.

Jonathan Basseri 59f0a99909 Fix equiv. cache invalidation of Node condition.
Equivalence cache for CheckNodeConditionPred becomes invalid when
Node.Spec.Unschedulable changes. This can happen even if
Node.Status.Conditions does not change, so move the logic around.

This logic is covered by integration test
"test/integration/scheduler".TestUnschedulableNodes but equivalence
cache is currently skipped when test pods have no OwnerReference.

Jonathan Basseri 30b89d830b Move scheduler code out of plugin directory.
This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.

Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.
