If we are dry-running, do not attempt to fetch the /version
resource and just return the stored FakeServerVersion,
which is done when constructing the dry-run client in
upgrade/common.go#getClient().
The problem here is that during upgrade
dry-run client reactors are backed by a dynamic client
via NewClientBackedDryRunGetterFromKubeconfig() and
for GetActions there seems to be no analog to
Discovery().Serverversion() resource for a dynamic client(?).
The kubeadm dry run client reactor code is flawed as it assumes
all invoked "get" verb actions can be casted to GetAction.
Apparently that is not the case when Discovery().ServerVersion()
and other discovery calls are made. In such cases the action
type is the bare ActionImpl.
Catch if an action can be casted to ActionImpl and construct a
GetAction from it. GetActionImpl only suppersets ActionImpl with
a Name field (empty string in this case).
Add unit test for Discovery().ServerVersion().
The NodePort functionality can be tested within the cluster.
Testing from outside the cluster assumes that there is connectivity
between the e2e.test binary and the cluster under test, that is not
always true, and in some cases is exposed to external factors or
misconfigurations like wrong routes or firewall rules that impact
on the test.

* Wire generic context to better handle timeout
* Add integration test for wait timeout
* kubectl wait: Fix integration test always passing issue
Currently, `kubectl wait` integration test always passes even if
it gets an error. Problem is object check is done after errexit is
turned off.
This PR redirects error to output and correctly assures that
object is expected status and if it is not, test should fail.
The background goroutine was started with the context from ginkgo.BeforeEach,
which then led to "context canceled" errors. While at it, the entire goroutine
start/stop gets moved into the BeforeEach and simplified.
These tests create their own pods, however, they were inside a block
that was always creating a pod, that was not used later on the tests,
but can influence on the conditions asserted to succeed the test.

Using the ctx of the ginkgo.BeforeEach in callbacks that are invoked after the
BeforeEach is done causes "context canceled" errors. Previously, this code used
context.TODO(). The best solution is to create a new context and cancel it
during test cleanup, then that context can be used for the API calls and as
stop channel.
After adding error checking in df5d84ae81, the "[sig-cli] Kubectl client
Simple pod should return command exit codes [Slow] running a failing command
without --restart=Never, but with --rm" test was found to time out.
Doubling the timeout might help. Alternatively, the entire
WaitForPodToDisappear could get removed, which would make this scenario similar
to the others which also don't wait.
the test uses a BeforeEach block to create a pod with the name defined
but the simplePodName variables, however, some test use the value of
the variable directly.
To avoid future problems use the variable name instead of the value on
all tests.
