Currently it's necessary for users to automatically add SerializationContextIntializer instances to the client via addContextInitializers and for .proto files to be registered like so:

Path proto = Paths.get(Query.class.getClassLoader().getResource("proto/sheep.proto").toURI());
cacheManager.getCache(ProtobufMetadataManagerConstants.PROTOBUF_METADATA_CACHE_NAME).put("sheep.proto", Files.readString(proto));

Instead we should allow users to configure the client so that:

1. SerializationContextInitalizer services are automatically registerd if builder.autoAddAllContextInitializers() is configured.
2. *.proto files on the classpath and in available SerializationContextInitializers are automatically registered with the server if .autoRegisterSchemas() is configured.

ProtoStreams AutoProtoSchemaBuilder already provides a `service` attribute to generate the service files for SerializationContextInitiailizer, however this is false by default. We should update this to true so that users have one less knob to confgure.

NOTE: autoRegisterSchemas() will fail if authorization is enabled and the client does not have the ___schema_manager role.
