Issue/Feature Description:
Use ConfigMap to enable soda-csi-provisioner to discover soda-proxy

Why this issue to fixed / feature is needed(give scenarios or use cases):
So that the image can be used without any changes in any env, as the service disovery will be configurable

[asifdxtreme]

Currently in our soda-csi-provisioner we use the service-name to discover the soda-proxy process, this doesn't works in most of the k8s development env.
We have hardcoded the service name of soda-proxy over here.

Alternatively we can also use configmap to expose the soda-proxy IP:port to soda-csi-provisioner, this solution will help soda-csi-porvisioner to discover the soda-proxy even in standalone env without need to any network config.
