Migrate from stable Helm-Chart

The following changes have been made compared to the stable chart: - [BREAKING CHANGE] The autolock feature was removed. Use configuration.startTime and configuration.endTime instead. - Role inconsistencies have been fixed (allowed verbs for modifying the DaemonSet, apiGroup of PodSecurityPolicy) - Added support for affinities. - Configuration of cli-flags can be made through a configuration object. - Added optional Service and ServiceMonitor support for metrics endpoint.
