New CRD and Controller: PersistentPodState

With the development of cloud native, more and more companies start to deploy stateful services (e.g., Etcd, MQ) using Kubernetes. K8S StatefulSet is a workload for managing stateful services, and it considers the deployment characteristics of stateful services in many aspects. However, StatefulSet persistent only limited pod state, such as Pod Name is ordered and unchanging, PVC persistence, and can not cover other states, e.g. Pod IP retention, priority scheduling to previously deployed Nodes.

So we provide PersistentPodState CRD to persistent other states of the Pod, such as "IP Retention".

For more detail, please refer to its documentation and proposal.
