- Add a package "node" under e2e/framework and alias e2enode;
- Rename some functions whose name have redundant string.

Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- net
- netexec
- nettest
- webhook
Many e2e tests expect two values are the same, such check is one of
common things in tests. Now gomega.Expect(foo).To(gomega.Equal(bar))
is doing that, this adds ExpectEqual() for replacing the above call
for readable code.
In addition, this replaces under apimachinery/generated_clientset.go
as a sample.
This fixes golint failures of the following files:
- test/e2e/framework/networking_utils.go
- test/e2e/framework/service_util.go
- test/e2e/framework/util.go
All golint failures in test/e2e/framework are fixed at this commit.
Remove 'test/e2e/framework' from 'hack/.golint_failures'
There is a lot of gomega.Expect(err).To(gomega.HaveOccurred()) callers
which expect an error happens in e2e tests.
However these test code seems confusing because the code readers
need to take care of To() or NotTo() on each test scenario.
This adds ExpectError() for more readable test code.
In addition, this applies ExpectError() to e2e provisioning.go as a
sample.
The framework/ssh.go code was heavily used throughout the framework
and could be useful elsewhere but reusing those methods requires
importing all of the framework.
Extracting these methods to their own package for reuse.
Only a few methods had to be copied into this package from the
rest of the framework to avoid an import cycle.
This test creates a pod with custom DNS configurations and expects
them to be set in the containers.
The test pod is using the agnhost image, which can output the container's
DNS configurations that the test checks.

It turns out to be a frequent bug that is revealed when nodes don't have
external IP addresses. In the test we assume that in such case there
won't be any addresses of type 'NodeExternalIp', which is invalid. In
such case there will be an address of type 'NodeExternalIP', but with
the empty 'Address' field.

2. works around https://github.com/kubernetes/kubernetes/issues/75338
which currently breaks vendoring
Some recent changes to crd_util.go must now be pulling in the broken
k8s.io/apiextensions-apiserver packages, because it was still working
in revision 2e90d92db9 (as demonstrated by
586ae281ac).
When running e2e conformance tests against a public https protected
APIserver the websocket tests would fail because it fell back to using
`ws://` instead of `wss://` for the websocket connection.
This happened because the code detect if HTTPS is used only looks for
HTTPS related configuration in the kubeconfig, like a custom CA or
certificates.
The fix is to always use HTTPS when the apiserver URL has the scheme `https://`.

The feature is gated behind a newly introduced 'dump-systemd-journal' flag.
We want to dump the full systemd journal in our scalability performance tests.
Some tests which utilized SSH to run commands on nodes would
first look for external IPs but fall back to internal IPs
since those could be reachable by the testing program.
This change adds that same fallback logic to another method
used to find the appropriate SSH address for each node.
Fixes#68747
While debugging issues I found myself having to change the constant in the code
for a cluster > 20 nodes, and then on a very small cluster I found myself passing
0 to avoid the mostly useless output (it's useful in specific scenarios but generates
a *lot* of output that doesn't help debugging the rest of the time).
Some mounttest related tests are checking the file permissions set on the
container files, but the default file permissions on Windows is 775 instead of
644, causing some tests to fail.
Keep in mind that file permissions work differently on Windows, and setting file
permissions via Kubernetes is not currently supported on Windows.
There were providers which would:
- allow overrides of the file base name but not the path
- allow oeverrides of the file path
- not allow any overrides at all
This change makes it such that each of the supported providers
can override the SSH key location using an env var. The env
var itself may vary based on the provider though.
If given an absolute path to the key, it is used. If given
a relative path it will be made relative to ~/.ssh
Fixes: #68747
Ginkgo expects the caller to pass the appropriate skip, which we do
not do. Slightly improve call site messages by eliding the util.go
stack frame. Also drop the timestamp from skip messages since skip
is almost always called to check for global conditions, not temporal
ones.

The existence of /proc/net/nf_conntrack depends on the Linux kernel
config CONFIG_NF_CONNTRACK_PROCFS, and Ubuntu 16.04's one is disabled.
So the e2e test "should set TCP CLOSE_WAIT timeout" fails on that.
This adds the existence check of /proc/net/nf_conntrack for skipping
the test if not existing.
In addition, this makes IssueSSHCommandWithResult return Stderr in
the error message if err is nil to check "No such file or directory"
as nonexistence of /proc/net/nf_conntrack.
This way we can be sure that the kubelet can't communicate with the
master, even if falls-back to the internal/external IP (which seems to
be the case with DNS)
Issue #56787
When we get an unsupported provider message, it often isn't clear what
method actually failed - add more information to the error message.
Issue #70280
Not all users of the E2E framework want to run cloud-provider specific
tests. By splitting out the code it becomes possible to decide in
a E2E test suite which providers are supported.
This is achieved in two ways:
- the framework calls certain functions through a provider
interface instead of calling specific cloud provider functions
directly
- tests that are cloud-provider specific directly import the
new provider packages
The ingress test utilities are only needed by a few tests. Splitting
them out into a separate package makes the framework simpler for test
suites not using those tests.
Fixes: #66649
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.

Handle TERM signal to reduce pod terminating time.
**What this PR does / why we need it**:
Register signal handler for `TERM`.
For container, process is run as PID 1. PID 1 is special in linux, it ignore any signal with the default action. So process will not terminate on `SIGINT` or `SIGTERM` unless it is coded to do so.
By default, docker use `TERM` signal to termiante pods, it will wait 10 seconds before sending `KILL` signal.
```
$ docker run -d --rm --name test busybox sh -c 'while true; do sleep 1; done'
aa827df5d7bfffc5ca4fae2429d0b761a5a142c57ba3e1faa59b305c92f1c875
$ time docker stop test
test
real 0m10.408s
user 0m0.048s
sys 0m0.020s
```
It's better to register a exit handler for `TERM`, it reduces a lot of time in waiting pods to termiante.
```
$ docker run -d --rm --name test busybox sh -c 'trap exit TERM; while true; do sleep 1; done'

Wait longer in pod cleanup
I've checked the [garbage collector tests](827b3d77cd/test/e2e/apimachinery/garbage_collector.go (L557)) and usually they're waiting up to a minute to clean the resources. So I'm proposing to use that same values when waiting for the pod cleanup.

Fixing kubemci conformance tests
Ref https://github.com/GoogleCloudPlatform/k8s-multicluster-ingress/issues/131
Changes:
* Add a static ip annotation while running the tests for kubemci. kubemci requires the IP to be preallocated.
* Add a default backend service. I have added it in the spec directly, so the change will be for ingress controller as well which should be fine. kubemci requires users to specify a default backend service that they need to ensure exists in all clusters.
* Disabled update SSL cert test for kubemci since it does not support that.
* Minor logging fixes.
Verified by running the tests locally that they now pass.
