remove unused func in FakeConfigurator of scheduler
**What this PR does / why we need it**:
Current scheduler `Configurator` interface looks like this:
```
type Configurator interface {
GetPriorityFunctionConfigs(priorityKeys sets.String) ([]algorithm.PriorityConfig, error)
GetPriorityMetadataProducer() (algorithm.PriorityMetadataProducer, error)
GetPredicateMetadataProducer() (algorithm.PredicateMetadataProducer, error)
GetPredicates(predicateKeys sets.String) (map[string]algorithm.FitPredicate, error)
GetHardPodAffinitySymmetricWeight() int32
GetSchedulerName() string
MakeDefaultErrorFunc(backoff *util.PodBackoff, podQueue core.SchedulingQueue) func(pod *v1.Pod, err error)
// Needs to be exposed for things like integration tests where we want to make fake nodes.
GetNodeLister() corelisters.NodeLister
GetClient() clientset.Interface
GetScheduledPodLister() corelisters.PodLister
Create() (*Config, error)
CreateFromProvider(providerName string) (*Config, error)
CreateFromConfig(policy schedulerapi.Policy) (*Config, error)
CreateFromKeys(predicateKeys, priorityKeys sets.String, extenders []algorithm.SchedulerExtender) (*Config, error)
}
```
Funcs `ResponsibleForPod` and `Run` once existed have been removed, so the funcs in `FakeConfigurator` should be removed accordingly.
**Special notes for your reviewer**:
/kind cleanup
/sig scheduling

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.
This changes the equivalence class hashing function to use as inputs all
the Pod fields which are read by FitPredicates. Before we used a
combination of OwnerReference and PersistentVolumeClaim info, which was
a close approximation. The new method ensures that hashing remains
correct regardless of controller behavior.
The PVCSet field can be removed from equivalencePod because it is
implicitly included in the Volume list.
Tests are now broken.
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.

fix the wrong err print of assumepod
**What this PR does / why we need it**:
I think the err print is wrong, just opposite the original meaning.

-Add scheduler optimization options, short circuit all predicates if …
…one predicate fails
Signed-off-by: Wang Guoliang <iamwgliang@gmail.com>
**What this PR does / why we need it**:
Short circuit all predicates if one predicate fails.
I think we can add a switch to control it, maybe some scenes do not need to know all the causes of failure, but also can get a great performance improvement; if you need to fully understand the reasons for the failure, and accept the current performance requirements, can maintain the current logic. It should expose this switch to the user.

**Release note**:
```
Allow scheduler set AlwaysCheckAllPredicates, short circuit all predicates if one predicate fails can greatly improve the scheduling performance.

- Remove string decode logic. It's not really helping to find the
conflict ports, and it's expensive to do encoding/decoding
- Not to parse the container ports information in predicate meta, use
straight []*v1.ContainerPort
- Use better data structure to search port conflict based on ip
addresses
- Collect scattered source code into common place
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.
Balanced Resource Allocation policy can now be enabled to so that
host(s) with balanced resource usage would be preferred. The score
given by BRA also scales from 0 to 10 with 10 representing that the
resource usage is well balanced.
* Improper format specifier (e.g. %s for bools or %s for ints)
* More or less parameters than format specifiers
* Not calling a formatting function when it should have (e.g. Error() instead of Errorf())
Replaces the client public interface but leaves old references to "minions"
for a later refactor. Selects the path "nodes" for v1beta3 and "minions"
for older versions.
Also rename some to other names that make better reading. There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things. It seemed that "make" there seemed fine. "New"
is for "constructors".
