the OTLP exporter added validation for the endpoint in #9505, but that configuration uses configgrpc for its endpoint. My question is whether this validation should be moved to configgrpc instead of the otlpexporter module to allow all consumers of configgrpc to benefit from this added validation.

On the other side of the argument, its possible consumers wouldn't want this validation, but i'm not sure if there's a good use-case for this.
