kubectl: make edit work with lists again
@kubernetes/kubectl this is fixing https://github.com/kubernetes/kubernetes/issues/20519 and slightly changes the behavior of --recursive when the directory that is being edited has files with errors. Previously since `edit` was working on an object basis, bad objects would be skipped and the editor would load the next object. We want to load multiple objects in the same list and it's impossible to load invalid objects in a list so --recursive will not work if there is any error in the directory. I think this is an acceptable trade-off.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

e2e.go/kops: Bump timeout to 20m, fix KUBERNETES_PROVIDER
**What this PR does / why we need it**: I don't have a ton of proof, but I think https://k8s-testgrid.appspot.com/google-aws#kops-aws-updown builds 4045-4047 are just AWS and DNS slowness.
In addition, my original PR was meant to change `KUBERNETES_PROVIDER` based on `KUBERNETES_CONFORMANCE_PROVIDER`.
Along the way: Fix ginkgo-e2e.sh. This change got dropped in the
original PR, but it was meant to allow a conformance-style
kubectl-auth test and still have a legit cloud provider.

make localupcluster work with RBAC enabled
When `ENABLE_RBAC=true` is set to true, `local-up-cluster` fails because it can't reach the endpoint (get a 403). This changes to an endpoint that the default policy allows anyone to see.
We can put subdomains into hosted zones (for example,
foo.federation.example.com can be hosted in example.com)
By allowing sharing a common hosted zone, this means the user doesn't
have to do as much setup.

fixed some issues with kubectl set resources
when using kubectl set resources it resets all resource fields that are not being set.
for example
# kubectl set resources deployments nginx --limits=cpu=100m
followed by
# kubectl set resources deployments nginx --limits=memory=256Mi
would result in the nginx deployment only limiting memory at 256Mi with the previous
limit placed on the cpu being wiped out. This behavior is corrected so that each invocation
only modifies fields set in that command and changed the testing so that the desired behavior
is checked.
Also a typo:
you must specify an update to requests or limits or (in the form of --requests/--limits)
corrected to

Implemented both the dry run and local flags.
Added test cases to show that both flags are operating as intended.

Build: Use checksum to rsync results
If dependencies are touched, the Makefile will detect that tools like
deepcopy-gen need to be rebuilt. It will rebuild them, but if Go decides the
dependencies are not ACTUALLY updated (maybe it was a test file - known
limitation of the current Makefile), it does not touch the resulting binary.
The Makefile touches the result explicitly to mark that the dep change has
been handled. But rsync blows away that change with the older file, and
helpfully preserves the timestamp. This repeats on every build.
Now rsync ignores it if the checksum is the same. Result = faster build.
