Determine when to apply gRPC ServerInterceptorFilter and ServerServiceDefinitionFilter

[philwebb]

In the current Spring gRPC auto-configuration the ServerInterceptorFilter and ServerServiceDefinitionFilter beans only apply automatically to in-process servers.

We'd like to keep things consistent and either not apply them directly to any server or always apply them to all servers.

There are some downsides with applying things automatically because whilst the ServerServiceDefinitionFilter can make a filter decision based on the GrpcServerFactory, the ServerInterceptorFilter cannot. Perhaps an update can be made to Spring gRPC for that?
