This commit adds two new collectors to the adapter: - ClusterScalingScheduleCollector; and - ScalingScheduleCollector Also, it introduces the required collectors plugins, initialization logic in the server startup, documentation and deployment example (including the helm chart). A new config flag is created, `-scaling-schedule`, and allows to enable and to disable the collection of such metrics. It's disabled by default. This collectors are the required logic to utilise the CRDs introduced in the #284 pull request. It makes use of the kubernetes go-client implementations of a [Store][0] and [Reflector][1].
