Application practice optimization suggestions for building Nebula clusters in Aliyun cloud

[0xRad7]

Hi, Nebula-operator Dev Team:
When I was using nebula-operator recently, I found a rather interesting place.
Currently nebula-operator only supportsthe storageClassName to create storage dynamically, when I practice building clusters on the cloud. AliCloud provides local storage (NVMe SSD) ECS to save half of the build cost when I creating a container cluster, and in my scenario I was able to get an additional 2TB of cloud disk space on this cluster.
However, the nebula-operator needs to provide a mechanism for setting up PVCs for the services, otherwise it will not be possible to configure existing PVs.

Yes, nebula-operator doesn't support configure existing PV for each component. More accurately, local storage is not supported either.
