Expose the storage provider endpoint as a configmap

[ashishmax31]

As an SRE we would like to build some scripts/automation around the odf-provider addon to retrieve the storage provider endpoint and supply it to the customer/CEE teams.

Proposal:
The operator creates a configmap containing the StorageProviderEndpoint string in the operator's namespace.

apiVersion: v1
kind: ConfigMap
metadata:
  name: ocs-storage-provider-endpoint
data:
  storage_provider_endpoint: <storage provider endpoint>
