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].
