[#889] review: * set response-required=false and requested-acks=twin-persisted via DittoHeadersBuilder (accept cloudevent requests with a 202 once persisted) * undid initializing DittoProtocolAdapter in a special way as this is not required * fixed that AbstractShardedPersistenceActor did not send back errors when response-required=false and requested-acks=twin-persisted was set in combination * applied codeformatter / organized imports * adjusted log statements to contain "CloudEvent" * adjusted some javadocs
