Add `kubectl attach` support for multiple types

To address this issue: https://github.com/kubernetes/kubernetes/issues/24857
the new `kubectl attach` will contain three scenarios depend on args:
1. `kubectl attach POD` :   if only one argument provided, we assume it's a pod name
2. `kubectl attach TYPE NAME` : if two arguments provided, we assume first one is resource we [supported](https://github.com/shiywang/kubernetes/blob/4770162fd3fd0d65ff95348c71683cf4c717141a/pkg/kubectl/cmd/util/factory_object_mapping.go#L285), the second resource's name.
3. `kubectl attach TYPE/NAME` : one argument provided and arg[0] must contain `/`, ditto

Is there any other scenarios I haven't consider in ?

for now the first scenario is compatible with changed before, also `make test` pass ✅ 
will write some unit test to test second and third scenario, if you guys think i'm doing the right way.

Use privileged containers for statefulset e2e tests

Test containers need to run as spc_t in order to interact with the host
filesystem under /tmp, as the tests for StatefulSet are doing. Docker
will transition the container into this domain when running the container
as privileged.

Add OWNERS file for GCE cloud provider

GCE cloud provider does not have OWNERS file and all PRs need to be approved by owner of pkg/cloudprovider, which is currently only @mikedanese. Adding more options would be helpful to speed up reviews.

Feel free to add/remove some names, this first version is just my qualified guess. It's hard to distinguish generic Kubernetes refactoring from real cloud provider work in git log.

Make DeltaFIFO Resync atomic

Make DeltaFIFO's Resync operation atomic, so it enqueues the entire

I'm hoping to use this to help with custom resync periods for multiple event handlers against a single shared informer (see https://github.com/kubernetes/kubernetes/pull/40759#pullrequestreview-19598213 for the motivation).

Default target storage in etcd

To make etcd v2->v3 upgrade work correctly, we need to correctly set the "TARGET_STORAGE" env var. Since in head we are defaulting to etcd v3, this PR is defaulting also that env var to etcd3, so that by default upgrade works fine.

[Kubelet] Delay deletion of pod from the API server until volumes are deleted

Previous PR that was reverted: #40239.

To summarize the conclusion of the previous PR after reverting:
- The status manager has the most up-to-date status, but the volume manager uses the status from the pod manager, which only is as up-to-date as the API server.
- Because of this, the previous change required an additional round trip between the kubelet and API server.
- When few pods are being added or deleted, this is only a minor issue.  However, when under heavy load, the QPS limit to the API server causes this round trip to take ~60 seconds, which is an unacceptable increase in latency. Take a look at the graphs in #40239 to see the effect of QPS changes on timing.
- To remedy this, the volume manager looks at the status from the status manager, which eliminates the round trip.

avoid repeated length calculation and some other code improvements

**What this PR does / why we need it**:
1. in function `ParsePairs`,  calculating `invalidBuf`'s length over and over again brings performance penalty. a `invalidBufNonEmpty` bool value can fix this.
2. pairArg is not a string template and also there is no other arguments for `fmt.Sprintf`, so i remove `fmt.Sprintf`
3. in function `DumpReaderToFile`, we must check nil error first before defer statement, otherwise there maybe a potential nil error on `f.Close()`
4. add nil checks into `GetWideFlag` function
5. some other minor code improvements for better readability.

Default the version to the information in federation versions file if $KUBERNETES_RELEASE isn't set.

Also, slightly unrelated fix: copy the output from the build container
to the host filesystem while building hyperkube image. The recent change
in the build scripts has caused the binaries to be not copied to the
required locations. It must be explicitly copied by calling the build copy
function.
