• If loglevel provided is not supported then we fail with validation error.

@Cryptophobia can you review this

Hey, looks good. Only a minor mistake in the camel case and we need to add the same env var in the values.yaml file.

[Cryptophobia]

@kkapoor1987 , can you also add it to the env vars in the docs here: https://github.com/vmware/kube-fluentd-operator#synopsis with a small description. Also, make sure to say --log-level is for config-reloader and --fluentd-loglevel is for fluentd container log level.
