Deprecated ports and schemas in Kubernetes cluster state templates

Currently we have deprecated ports and schemas for Controller Manager and Scheduler cluster components in these templates:

• Kubernetes Controller manager by HTTP
• Kubernetes Scheduler by HTTP
• Kubernetes cluster state by HTTP

Following changes should be made:

• {$KUBE.CONTROLLER_MANAGER.PORT}: 10252 -> 10257
• {$KUBE.CONTROLLER_MANAGER.SCHEME}: http -> https
• {$KUBE.CONTROLLER.SERVER.URL}: http://localhost:10252/metrics -> https://localhost:10257/metrics
• {$KUBE.SCHEDULER.PORT}: 10251 -> 10259
• {$KUBE.SCHEDULER.SCHEME}: http -> https
• {$KUBE.SCHEDULER.SERVER.URL}: http://localhost:10251/metrics -> https://localhost:10259/metrics

Also it should be noted in READMEs, that setting up --bind-address option for Scheduler and Controller Manager components might be required, so that Zabbix proxy would be able to reach them.
