Add a test case with a DaemonSet behind a simple load balancer whose
address is being constantly hit via HTTP requests.
The test passes if there are no errors when doing HTTP requests to the
load balancer address, during DaemonSet `RollingUpdate` operations.

Adding the "context" import in the previous commit must get compensated by
removing one of the blank lines in the output unit tests, otherwise the stack
backtrace don't match expectations.
Adding "ctx" as parameter in the previous commit led to some linter errors
about code that overwrites "ctx" without using it.
This gets fixed by replacing context.Background or context.TODO in those code
lines with the new ctx parameter.
Two context.WithCancel calls can get removed completely because the context
automatically gets cancelled by Ginkgo when the test returns.
Every ginkgo callback should return immediately when a timeout occurs or the
test run manually gets aborted with CTRL-C. To do that, they must take a ctx
parameter and pass it through to all code which might block.
This is a first automated step towards that: the additional parameter got added
with
sed -i 's/\(framework.ConformanceIt\|ginkgo.It\)\(.*\)func() {$/\1\2func(ctx context.Context) {/' \
$(git grep -l -e framework.ConformanceIt -e ginkgo.It )
$GOPATH/bin/goimports -w $(git status | grep modified: | sed -e 's/.* //')
log_test.go was left unchanged.
Endpoints generated by the endpoints controller are in the canonical
form, however, custom endpoints can not be in canonical format
(there was a time they were canonicalized in the apiserver, but this
caused performance issues because the endpoint controller kept
updating them since the created endpoint were different than the
stored one due to the canonicalization)
There are cases where a custom endpoint may generate multiple slices
due to the controller, per example, when the same address is present
in different subsets.
The endpointslice mirroring controller should canonicalize the
endpoints subsets before start processing them to be consistent
on the slices generated, there is no risk of hotlooping because
the endpoint is only used as input.

Currently, if user executes `kubectl scale --dry-run`, output has no
indicator showing that this is not applied in reality.
This PR adds dry run suffix to the output as well as more integration
tests to verify it.
`kubectl scale` calls visitor two times. Second call fails when
the piped input is passed by returning an
`error: no objects passed to scale` error.
This PR uses the result of first visitor and fixes that piped
input problem. In addition to that, this PR also adds new
scale test to verify.
`kubectl exec` command supports getting files as inputs. However,
if the file contains multiple resources, it returns unclear error message;
`cannot attach to *v1.List: selector for *v1.List not implemented`.
Since `exec` command does not support multi resources, this PR
handles that and returns descriptive error message earlier.
In the Dynamic Resource allocation example specs, the claim
parameter name specified was inconsistent.
This commit fixes that with a better/more consistent name,
which is used to define the configmap and referenced in
the `ResourceClaimTemplate` spec.
