WLI: configuring JMS queues for performance

The JMS queues AsyncDispatcher and AsyncDispatcher_error are needed for each project containing process.
All WLI process are based on these 2 queues, and it is therefore necessary to configure them properly.

For the queue AsyncDispatcher:
- Retry => 0 or a low value with a redelivery delay set. The retry may be useful in case of unavailability of external system.
- Error destination => AsyncDispatcher_error.

For the queue AsyncDispatcher_error:
- Retry => maximum value in order not to lose messages.
- Redelivery delay positioned so as not to saturate the server.
