Fixed `The phase of Pod e2e-test-pod is Succeeded which is unexpected`
error. `e2epod.NewPodClient(f).CreateSync` is unable to catch 'Running'
status of the pod as pod finishes too fast.
Using `Create` API should solve the issue as it doesn't query pod
status.

The runtime classes are apiserver's concept, while the handlers are kubelet's concept.
For NodeStatus, it makes more sense to return the latter ones here.

* Add e2e tests for Service.spec.trafficDistribution
* Fix linting issue
* Fix spelling
* Add integration tests for trafficDistribution
* Use nodeSelection instead of nodeName to schedule pods on a specific zonal node
* Fix import alias corev1 -> v1 in e2e test
* Address comments
* Add a way to only print log lines in case of errors. This is deemed to be good behaviour by e2e tests guidelines
It turns out that kube has a custom timeout for tests of 3 minutes.
The tests in the cacher package are utilizing nearly the
entire time and are being terminated, resulting in failing jobs.
Before the change, the TestWatchSemantics took ~43s to run. With this simple change, it now takes ~18s.
When we created the tests, we didn't measure the running time and assumed that waiting 1 second on a watch channel
to make sure no more events are received was sufficient.
This PR decreases the waiting time to 300 milliseconds.
Modern computers can perform many tasks within that time.
In addition to that, the tests are serial in nature, meaning that there is no other
actor that could add items to the database, which could result in receiving new items.
After the change the total running time decreased by 17%.
Before the tests needed ~176s after they need ~146s.
The changes also improved TestWatchSemanticInitialEventsExtended.
updates the test to wait 300 ms instead of 3s
the watch was established otherwise
we would be blocking on a call to cache.Watch(...)
