Jonathan Basseri 95254d5457 Move CacheDebugger signal handling into the package. 
This moves the signal handling for CacheDebugger from the factory
package into the CacheDebugger's package. That makes it easier to reuse
from packages other than factory.

Jonathan Basseri 8e25361320 Move `ScheduleAlgorithm` to the core package. 
This moves the type `ScheduleAlgorithm` from `pkg/scheduler/algorithm`
to `pkg/scheduler/core`. The reason for this move is to fix our import
dependency graph and allow predicate & priority types to be moved into
their appropriate packages.

The new location makes sense because `core` is the only package that
exports an implementation of this type.

Gregory Haynes 5e4ccede4c Reschedule with backoff 
With the alpha scheduling queue we move pods from unschedulable to
active on certain events without a backoff. As a result we can cause
starvation issues if high priority pods are in the unschedulable queue.
Implement a backoff mechanism for pods being moved to active.

Closes #56721
 2018-12-06 16:38:34 +00:00
Gregory Haynes 082b48240a Implement scheduler.util.backoff as a queue 
We are going to use PodBackoff for controlling backoff when adding
unschedulable pods back to the active scheduling queue. In order to do
this more easily, limit the interface for PodBackoff to only this struct
(rather than exposing BackoffEntry) and change the backing expiry
implementation to be queue based.

Jonathan Basseri b864a5a808 Remove scheduler "TestGroup" utility. 
This util was used to fake certain aspects of apiserver behavior, such
as resource paths and JSON encoding. Our unit tests have been refactored
so they don't rely on the REST or JSON aspects of apiserver. This util
is no longer needed.

ensure scheduler preemptor behaves in an efficient/correct path 
- don't update nominatedMap cache when Pop() an element from activeQ
- instead, delete the nominated info from cache when it's "assumed"
- unit test behavior adjusted
- expose SchedulingQueue in factory.Config

Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
