1fe7ce21bc refactor(scheduler): Move priority types to priorities package 
This moves the priority types from the algorithm package
to priorities package.
Idea is to move the type to the packages where it is
implemented. This will ease the future refactor process.

Merge pull request #71118 from ping035627/k8s-181115

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.

Reschedule with backoff
 2018-12-07 21:13:57 -08:00
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

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
