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.

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

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".

In contrast to the original HandleError and HandleCrash, the new
HandleErrorWithContext and HandleCrashWithContext functions properly do contextual
logging, so if a problem occurs while e.g. dealing with a certain request and
WithValues was used for that request, then the error log entry will also
contain information about it.
The output changes from unstructured to structured, which might be a breaking
change for users who grep for panics. Care was taken to format panics
as similar as possible to the original output.
For errors, a message string gets added. There was none before, which made it
impossible to find all error output coming from HandleError.
Keeping HandleError and HandleCrash around without deprecating while changing
the signature of callbacks is a compromise between not breaking existing code
and not adding too many special cases that need to be supported. There is some
code which uses PanicHandlers or ErrorHandlers, but less than code that uses
the Handle* calls.
In Kubernetes, we want to replace the calls. logcheck warns about them in code
which is supposed to be contextual. The steps towards that are:
- add TODO remarks as reminder (this commit)
- locally remove " TODO(pohly): " to enable the check with `//logcheck:context`,
merge fixes for linter warnings
- once there are none, remove the TODO to enable the check permanently

Currently type references for non-local names are output as relative
types which is subject to the resolution rules as defined at
https://protobuf.com/docs/language-spec#reference-resolution
This works fine within the k8s.io namespace where no subpackages are
named k8s, but other users of go-to-protobuf likely have k8s in their
package name. This causes conflicts in the search resolution when
executing `go-to-protobuf`:
```
company.example.com/k8s/custom/pkg/apis/custom.k8s.example.com/v1/generated.proto:64:12: "k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta" is resolved to "company.example.com.k8s.custom.pkg.apis.custom.k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta", which is not defined. The innermost scope is searched first in name resolution. Consider using a leading '.'(i.e., ".k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta") to start from the outermost scope.
```
To avoid this we can output fully qualified type references using a
preceding dot (.)
This results in a change for k8s generated.proto files, but the
effect is a noop.

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.

the watch was established otherwise
we would be blocking on a call to cache.Watch(...)

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