K8s/Deployment: Stand-alone deployment

[caoxianfei1]

Is your feature request related to a problem? (你需要的功能是否与某个问题有关?)

Now we can deploy three copies on three nodes, but the operator has not implemented stand-alone deployment, which is similar to curveadm's stand-alone deployment capability

Describe the solution you'd like (描述你期望的解决方法)

This function is actually not complicated. It needs to consider some judgment conditions, or add a field displayed on the API to express. The focus of this task is that port allocation needs to be considered when deploying all service on the one node.

you can refer curveadm's topology config file for one-host topology
