* First version of batching w/out signatures.
* First version of pod signatures.
* Integrate batching with signatures.
* Fix merge conflicts.
* Fixes from self-review.
* Test fixes.
* Fix a bug that limited batches to size 2
Also add some new high-level logging and
simplify the pod affinity signature.
* Re-enable batching on perf tests for now.
* fwk.NewStatus(fwk.Success)
* Review feedback.
* Review feedback.
* Comment fix.
* Two plugin specific unit tests.:
* Add cycle state to the sign call, apply to topo spread.
Also add unit tests for several plugi signature
calls.
* Review feedback.
* Switch to distinct stats for hint and store calls.
* Switch signature from string to []byte
* Revert cyclestate in signs. Update node affinity.
Node affinity now sorts all of the various
nested arrays in the structure. CycleState no
longer in signature; revert to signing fewer
cases for pod spread.
* hack/update-vendor.sh
* Disable signatures when extenders are configured.
* Update pkg/scheduler/framework/runtime/batch.go

When using context.CancelCause in the scheduler and context.Cause in plugins,
the status returned by plugins is more informative than just "context
canceled".
Context cancellation itself is not new, but many plugin authors probably
weren't aware of it because it wasn't documented.
* Move ClusterEvent type to staging repo, leaving some functions (that contain logic internal to scheduler) in kubernetes/kubernetes
apply review comment and fix linter warning

SharedDRAManager will be used by the DRA plugin to obtain DRA
objects, and to track modifications to them in-memory. The current
DRA plugin behavior will be the default implementation of
SharedDRAManager.
Plugging a different implementation will allow Cluster Autoscaler
to provide a simulated state of DRA objects to the DRA plugin when
making scheduling simulations, as well as obtain the modifications
to DRA objects from the plugin.
This enables connecting the event handler for ResourceClaim to the assume
cache, which addresses a theoretic race condition.
It may also be useful for implementing the autoscaler support, because now
the autoscaler can modify the content of the cache.
