extends com.google.protobuf.GeneratedMessageV3.Builder<CustomResponse.Builder>
implements CustomResponseOrBuilder
     The filter configuration is a collection of custom response
 policies in a matcher tree. The configuration can be defined at the filter,
 virtual host or route level. The response will be matched against the most
 specific to the least specific config, till a match is found.
