A feature similar to the HTTPCaller's 'rate limiting' options may be very useful for reading features from feature services. We very often get failures when reading feature services, when the feature service throws an error about 'Too many requests, API calls quota exceeded'. I've had to work around this by stringing together multiple FeatureReaders with Decelerators between them. These read 6000 features, then a Decelerator has the workspace pause for 65 seconds, then read the next 6000, so on and so forth. It'd be awesome if instead of this clunky workaround, we'd be able to just configure the FeatureReader/reader to only read a maximum of 6000 features per minute, or something along those lines.
