This PR addresses the issue that if the pb encoding fails the pipeline stops.
In order to reproduce just add a field to the event which is not present in the protobuf definition.
[WARN ] 2020-06-10 13:43:38.952 [[rum-akamai2bi]>worker1] protobuf - Protobuf encoding error 1: Argument error (#<ArgumentError: field bot is not found>). Reason: probably mismatching protobuf definition. Required fields in the protobuf definition are: user_agent, geo, dom, active_ctests, header, timestamp, domain, tracking_id and fields must not begin with @ sign. The event has been discarded.
[ERROR] 2020-06-10 13:43:38.954 [[rum-akamai2bi]>worker1] WorkerLoop - Exception in pipelineworker, the pipeline stopped processing new events, please check your filter configuration and restart Logstash.
