Currently users must provide a .jar containing SerializationContextInitializer implementations in the server/libs dir if they want .proto files to be registered on server startup. This is not user-friendly for non-java developers, as they will not have Pojos to annotate, therefore they cannot automatically generate such implementations. Instead, we should enhance the server so that it automatically detects */.proto fields in the server/lib directory and registers them on startup.

Providing such a capability will also simplify Helm Chart and Operator deployments, as it will be possible for users to simply provide a ConfigMap containing .proto definitions and we can mount this under server/libs.
