This is some light cleanup of logs in predicates.go. In particular, some
log lines have details clarified that will make debugging easier.
I have not touched any VLOG messages, since those usually have plenty of
detail.
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.
- Maintain list of default predicates and priorities in defaults.go
and move the registration to separate files

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.
- 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

From current AWS documentation:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html
T3, C5, C5d, M5, M5d, R5, R5d, and z1d instances support a maximum of
28 attachments, and every instance has at least one network interface
attachment. If you have no additional network interface attachments on
these instances, you could attach 27 EBS volumes.

Revert "Revert "Revert revert of equivalence class hash calculation i…

This reverts commit 4386751b5d.
**What this PR does / why we need it**:
This re-introduces the change from https://github.com/kubernetes/kubernetes/pull/58555 which changes how the scheduler computes equivalence classes of pods. I believe we have fixed the flakiness observed previously (https://github.com/kubernetes/kubernetes/issues/61512, https://github.com/kubernetes/kubernetes/issues/62921). I have run the test in question a few dozen times without a failure.
```bash
make test-integration WHAT="./test/integration/scheduler" KUBE_TEST_ARGS="-run TestPreemptionStarvation" GOFLAGS="-v"
