testify is used throughout the codebase; this switches mocks from
gomock to testify with the help of mockery for code generation.
Handlers and mocks in test/utils/oidc are moved to a new package:
mockery operates package by package, and requires packages to build
correctly; test/utils/oidc/testserver.go relies on the mocks and fails
to build when they are removed. Moving the interface and mocks to a
different package allows mockery to process that package without
having to build testserver.go.

See https://github.com/golang/mock#gomock: golang/mock is no longer
maintained, and should be replaced by go.uber.org/mock.
This allows golang/mock to be dropped from the status and vendored
fields in unwanted-dependencies.json.

Currently, there are some unit tests that are failing on Windows due to
various reasons:
- config options not supported on Windows.
- files not closed, which means that they cannot be removed / renamed.
- paths not properly joined (filepath.Join should be used).
- time.Now() is not as precise on Windows, which means that 2
consecutive calls may return the same timestamp.
- different error messages on Windows.
- files have \r\n line endings on Windows.
- /tmp directory being used, which might not exist on Windows. Instead,
the OS-specific Temp directory should be used.
- the default value for Kubelet's EvictionHard field was containing
OS-specific fields. This is now moved, the field is now set during
Kubelet's initialization, after the config file is read.
This change is to promote local storage capacity isolation feature to GA
At the same time, to allow rootless system disable this feature due to
unable to get root fs, this change introduced a new kubelet config
"localStorageCapacityIsolation". By default it is set to true. For
rootless systems, they can set this configuration to false to disable
the feature. Once it is set, user cannot set ephemeral-storage
request/limit because capacity and allocatable will not be set.

TestStart was previously flaky. In approx 100_000 local runs, it failed
about 70% of the time, and has been mentioned as a flaky unit test in
the past.
This flake was due to a race condition with the logic as written and the
go scheduler. UpdateThreshold calls `notifier.Start(events)` in a new Go
Routine, which is not guarunteed to be called immediately.
This meant that if `m.Start()` was called before `notifier.Start()`, the
test would fail, as the notifier would not have been started before the
4 events were processed and lock released.
Here, we update the test to more closely match the intended application
behaviour, and have events passed to the channel when `Start` is called
on the notifier.
This ensures that -Start gets called and additionally validates
that the correct channel is provided to the notifier.
Stop was never called previously, as it only gets called on a subsequent
call to UpdateThreshold. `AnyTimes()` hid that this did not occur.
In the following code pattern, the log message will get logged with v=0 in JSON
output although conceptually it has a higher verbosity:
if klog.V(5).Enabled() {
klog.Info("hello world")
}
Having the actual verbosity in the JSON output is relevant, for example for
filtering out only the important info messages. The solution is to use
klog.V(5).Info or something similar.
Whether the outer if is necessary at all depends on how complex the parameters
are. The return value of klog.V can be captured in a variable and be used
multiple times to avoid the overhead for that function call and to avoid
repeating the verbosity level.
