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.

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

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.
