Improve performance of affinity/anti-affinity predicate by 20x in large clusters
**What this PR does / why we need it**:
Improves performance of affinity/anti-affinity predicate by over 20x in large clusters. Performance improvement is smaller in small clusters, but it is still very significant and is about 4x. Also, before this PR, performance of the predicate was dropping quadratically with increasing size of nodes and pods. As the results shows, the slow down is now linear in larger clusters.
Affinity/anti-affinity predicate was checking all pods of the cluster for each node in the cluster to determine feasibility of affinit/anti-affinity terms of the pod being scheduled. This optimization first finds all the pods in a cluster that match the affinity/anti-affinity terms of the pod being scheduled once and stores the metadata. It then only checks the topology of the matching pods for each node in the cluster.
This results in major reduction of the search space per node and improves performance significantly.
Below results are obtained by running scheduler benchmarks:

Schedule even if extender is not available when using extender
**What this PR does / why we need it**:
When using scheduler extender, if the extender is not available scheduling of all pods fail.
We should let the scheduling happen but display error message that extender is failing.
`IsIgnorable()` is added to extender to indicate: if scheduling of all pods should fail when it's unavailable
**Backward compabtiility:**
We use `IsIgnorable` instead of `IsCritical` so that when this flag is not set, the default value will be `false`, i.e. not ignorable, which consistent with the current behavior in existing extenders.

**Special notes for your reviewer**:
Pods in scheduler cache contains both the scheduled pods and those not
scheduled yet in scheduling queue. This commit adds the second group of
pods into consideration while comparing the cache.
UID uniquely identifies pods across lifecycles, while namespace/name
could be 2 different pods across lifecycles. This could result in
tricky scheduler bugs.

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.
Add benchmark for equivalence hashing.
Change equivalence hash function.
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.
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.
Fix equivalence cache hash tests.

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.

Fix to register priority function ResourceLimitsPriority correctly.
**What this PR does / why we need it**:
This PR fixes registration of priority function ResourceLimitsPriority. Previously this function was being registered inside `init()`. Since this priority function ResourceLimitsPriority is behind feature gate `ResourceLimitsPriorityFunction` and if the feature is enabled, it was not visible in `init()` function. So now the registration of this priority function is moved inside `ApplyFeatureGates()` in scheduler where it can be correctly registered after the feature has been enabled.

Ensure euqiv hash calculation is per schedule
**What this PR does / why we need it**:
Currently, equiv hash is calculated per schedule, but also, per node. This is a potential cause of dragging integration test, see #58881
We should ensure this only happens once during scheduling of specific pod no matter how many nodes we have.

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.

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.

-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.

- 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".
