Travis: Initiating build for commit 'cd892181df95e73e9a44bd6f4d42939311fbb5a3' on branch 'processed_metrics_metadata': Use try-catch to get query params in PostProcessor when applying processed metrics filters, since getRequestVar won't return default value 'false' if type is 'integer'. No way to tell if query param has not been supplied or if value is default.
