hibernate - simply save kubernetes resource costs

This is a simple tool to save kubernetes resource costs. It will scale down deployments and statefulsets to 0 replicas at a scheduled time every day. It will also scale up the deployments and statefulsets to the original number of replicas at a scheduled time every day/days of a week. Primarily built to seemlessly tackle spinning down dev environments at night and weekends.
