[fabiorauber]

Is this a bug report or feature request?

• Feature Request

What should the feature do:
Allow the user to specify resources.requests and resources.limits for the NFS Server Statefulset.

What is use case behind this feature:
Like most Pods on a Kubernetes cluster, being able to specify resources requests and limits (both memory and CPU) helps to ensure the Pod has the necessary resources to work its magic, or to prioritize resources for this Pod over others.

Environment:
Any Kubernetes cluster with a Rook NFS Server deployed.
