Behavioural Changes

• REST onramp and offramp have changed their configuration quite a lot, please checkout the docs for the onramp and offramp for reference.
• The REST offramp no longer adds newlines for batched events, this can now be done by using the lines postprocessor.
• Heredocs in tremor-script
  • no longer strip leading indentation
  • string interpolation using curly braces"""field: {event["field"]}""" has been added to heredocs
  • Literal curlies now need to be escaped using \{ or{{
• The generic::backpressure operator has been renamed to qos::backpressure.
• All operators have been streamlined to have their error output renamed to err, namely runtime::tremor, grouper::bucket and script inside trickle. Now pipelines, onramps, offramps and operators all output error events to err.
