Remove a plugins can lead to stop of executor

🆚 [context: default] [date: 2022-05-18T15:37:37.838Z] [logger: org.apache.kafka.clients.consumer.internals.ConsumerCoordinator] [severity: WARN] [thread: kafka-coordinator-heartbeat-thread | kestra_executor_main] [Consumer instanceId=dev-kestra-executor-d555865d6-88cp5-1, clientId=io.kestra.runner.kafka.executors.ExecutorMain-StreamThread-1-consumer, groupId=kestra_executor_main] consumer poll timeout has expired. This means the time between subsequent calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time processing messages. You can address this either by increasing max.poll.interval.ms or by reducing the maximum size of batches returned in poll() with max.poll.records.

This is caused I think because we wait for the flow and will never found it (invalid flow maybe because of invalid type?). Seems the executor :

• is waiting
• raise the error consumer poll timeout has expired
• the consumer group is removed from kafka
• no more activity and freeze
