The project does not recommend using insecure ports. Even
unauthenticated TLS is an improvement since it provides confidentiality.
If you relied upon this, please update to secure serving options.

apiserver/storage/cacher: decrease of running time of TestWaitUntilWatchCacheFreshAndForceAllEvents

Fix non-recursive list returning "resource version too high" error when consistent list from cache is enabled
Kubernetes-commit: 3409f0594c94185010217f3e5156c1de9f08b405
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(...)
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.

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.

since we don't provide compatibility guarantees for the storage
package it is okay to simply remove unused function.

Stop using defer as parallel subtest will might result in main test
finishing before subtest.
Fatal when same flag is set twice.

The code in ConvertToType checked for conversion into typeValue (=
"kubernetes.URL") instead of conversion into quantityTypeValue (=
"kubernetes.Quantity") and thus most likely failed with an incorrect "type
conversion error".
