Delete evicted pet
If pet was evicted by kubelet - it will stuck in this state forever.
By analogy to regular pod we need to re-create pet so that it will
be re-scheduled to another node, so in order to re-create pet
and preserve consitent naming we will delete it in petset controller
and create after that.

Fix issue in updating device path when volume is attached multiple times
When volume is attached, it is possible that the actual state
already has this volume object (e.g., the volume is attached to multiple
nodes, or volume was detached and attached again). We need to update the
device path in such situation, otherwise, the device path would be stale
information and cause kubelet mount to the wrong device.

Fix#33784, IN_CREATE event does not guarantee file content written
Fixed#33784.
The CREATE inotify event [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/config/file_linux_test.go#L275) is triggered by os.OpenFile(), however the content would be written by the following f.Write(). It will fail if the program try to process the event in between.
IN_CREAE event is triggered by open(2), mkdir(2), link(2), symlink(2), bind(2), but not all of them will guarantee the content is written ([ref](http://man7.org/linux/man-pages/man7/inotify.7.html)). <s>Hence we should not respond to IN_CREATE event for pod creation. I believe listen on IN_MODIFY and IN_MOVED_TO would be sufficient for pod addition&update.
Would like to see the Jenkins test results for further evaluation.

Split NodeDiskPressure into NodeInodePressure and NodeDiskPressure
Added NodeInodePressure as a NodeConditionType. SignalImageFsInodesFree and SignalNodeFsInodesFree signal this pressure. Also added simple pieces to the scheduler predicates so that it takes InodePressure into account.

Add seccomp and apparmor support.
This PR adds seccomp and apparmor support in new CRI.
This a WIP because I'm still adding unit test for some of the functions. Sent this PR here for design discussion.
This PR is similar with https://github.com/kubernetes/kubernetes/pull/33450.
The differences are:
* This PR passes seccomp and apparmor configuration via annotations;
* This PR keeps the seccomp handling logic in docker shim because current seccomp implementation is very docker specific, and @timstclair told me that even the json seccomp profile file is defined by docker.
Notice that this PR almost passes related annotations in `api.Pod` to the runtime directly instead of introducing new CRI annotation.

e2e.go / kops: Add ssh-key option to override ssh key
**What this PR does / why we need it**: By default, Jenkins stuffs the ssh key in `/workspace/.aws/kube_aws_rsa`. This allow the SSH key to be overridden easily on the command line.
We weren't getting incremental builds because of new test only subpackages. Our
voodoo combo of 'go install' and 'go test -c' didn't cache things like
'test/e2e_node/services'. Add the '-i' flag to 'go test' to install test only
dependencies too.
make-generated-{protobuf,runtime}.sh was doing some really nasty stuff with how
the build container was managed in order to copy results out. Since we have
more flexibility to grab results out of the build container, we can now avoid
all of this. Ideally we wouldn't have `hack` calling `build` at all, but we
aren't there yet.
We also add "version" to all docker images and containers
This version is to be incremented manually when we change the shape of the build
image (like changing the golang version or the set of volumes in the data
container). This will delete all older versions of images and containers when
the version is different.

wait for federation informer store to catch up before update
Fixes#33838#33880
There is a flake in the federation-controller code where an update to a resource is done too quickly after the create. Because the resource is not yet in the federated informer store, when the reconcile<Resource>() is called, it can't find the resource and treats the change as a create rather than a update.
This causes a failure (actually a panic) in the test code, which expects an update event, not a create, in response to the resource modification.

DeltaFIFO should not report HasSynced until deletes are reported
Deletions identified by knownObjects on the initial sync replace
(immediately after the List from a reflector) should be considered part
of the initial sync since we have the information available at the time
we do the deletion.
An error during Replace() can result in Populated not being set, but it
was incorrect before (population would be wrong) and queueActionLocked
does not error except on "my cache is broken because I gave an incorrect
keyFunc".
@lavalamp @deads2k hit this while trying to use DeltaFIFO to implement an "external" controller (one that uses the knownObjects as provided by a call to a remote system of record).

CRI: Fix bug in dockershim to set sandbox id properly.
For https://github.com/kubernetes/kubernetes/issues/33189#issuecomment-249307796.
During debugging `Variable Expansion should allow composing env vars into new env vars`, I found that the root cause is that the sandbox was removed before all containers were deleted, which caused the pod to be started again after succeed.
This happened because the `PodSandboxID` field is not set. This PR fixes the bug.
Some other test flakes are also caused by this
```
Downward API volume should provide node allocatable (cpu) as default cpu limit if the limit is not set
Downward API volume should provide container's memory limit
EmptyDir volumes should support (non-root,0666,tmpfs)
...

Fix summary test
Issue was comparing an `unversioned.Time` rather than `time.Time`. I temporarily removed the `[Flaky]` tag so the PR builder will run the test. I will revert that change before submitting.
