JEC fails to execute zabbix server script

When trying to acknowledge an alarm from JSM using **zabbix-1.0.3_jec-1.0.4**, JEC action handler starts, but fails calling out to the python script with:

```
Received 1 messages from the queue[...].
Job[...] is being submitted
Job[...] is submitted to worker[...]
Message[...] is deleted from the queue[...].
Action[Acknowledge] execution of message[...] failed: exit status 2 Stderr: usage:
jec_action_executor.py [-h]
-payload QUEUEPAYLOAD -apiKey APIKEY -jsmUrl JSMURL -logLevel LOGLEVEL
[-command_url COMMAND_URL] [-user USER] [-password PASSWORD]
jec_action_executor.py: error: unrecognized arguments:
--jecNamedPipe /var/tmp/jec/jecCallbackPipe-...
Job[...] has been processed by worker[...].
Current Worker: 4, Idle Worker: 4, Queue Size: 0, Queue load: 0
Successfully sent result of message[...] to Jira Service Management and it took 0.800652 seconds.
```

Start by locating jec_action_executor.py and inspect its argument handling alongside the JEC action invocation that passes --jecNamedPipe. Reproduce the acknowledge-alarm flow using the versions named in the report, then confirm that the action completes without the unrecognized-argument error and still returns its result to Jira Service Management.
