Fix a TODO to plumb an update filter from above in the resource quota
monitor code that was handling update events for quota-able objects,
instead of hard-coding the logic in the resource quota monitor.

* kubelet: silence flag output on errors
Currently, the `--help` text is output on kubelet errors. Currently on
my machine this is 280 lines. Typically kubelet is run by systemd or
similar, starting it a loop. This means when an issue is encountered, we
are spammed by 100s of logs per second, masking the real error.
With this PR, the list of all flags is silenced. Users can still access
them by `kubelet --help` as normal. This same `SilenceUsage` is already
set in the api-server command.
* Update cmd/kubelet/app/server.go

- `cert-dir` could be specified to a value other than the default value
- we have tests that should be executed successfully on the working cluster

It is useful to have the ability to control whether alpha or beta features are
enabled. We can group features under LoggingAlphaOptions and LoggingBetaOptions
because the configuration is designed so that each feature individually must be
enabled via its own option.
Currently, the JSON format itself is beta (graduated in 1.23) but additional
options for it were only added in 1.23 and thus are still alpha:
$ go run ./staging/src/k8s.io/component-base/logs/example/cmd/logger.go --logging-format=json --log-json-split-stream --log-json-info-buffer-size 1M --feature-gates LoggingBetaOptions=false
[format: Forbidden: Log format json is BETA and disabled, see LoggingBetaOptions feature, options.json.splitStream: Forbidden: Feature LoggingAlphaOptions is disabled, options.json.infoBufferSize: Forbidden: Feature LoggingAlphaOptions is disabled]
$ go run ./staging/src/k8s.io/component-base/logs/example/cmd/logger.go --logging-format=json --log-json-split-stream --log-json-info-buffer-size 1M
[options.json.splitStream: Forbidden: Feature LoggingAlphaOptions is disabled, options.json.infoBufferSize: Forbidden: Feature LoggingAlphaOptions is disabled]
This is the same approach that was taken for CPUManagerPolicyAlphaOptions and
CPUManagerPolicyBetaOptions.
In order to test this without modifying the global feature gate in a test file,
ValidateKubeletConfiguration must take a feature gate as argument.
