Job timeout should be handled by the executor

[fmbenhassine]

As of version 4, the "timeout" parameter allow to abort execution if the whole processing time exceeds the defined timeout. The problem is that the job will check the timeout after each processed record (in between records). Hence, if a processor runs indefinitely, the timeout is not respected.

Moreover, handling job timeout should be done using the executor. It's not the job role to handle timeout.

"timeout" parameter should be deprecated in v4.2 and removed in v5
