Add vhost --default-queue-type option

[alborzjafari]

Description of the change

• This commit adds the --default-queue-type option as described in the documentation.
• To test the change, set the RABBITMQ_VHOSTS environment variable. For example:

  RABBITMQ_VHOSTS=queue_name_0:classic queue_name_1:quorum queue_name_2:stream
  

• If a queue name is specified without a queue type, it will use the default type:

  RABBITMQ_VHOSTS=queue_name_0 queue_name_1:quorum
  

Benefits

In some cases (including mine), it is not possible to change the default queue type from the application source code; therefore, it should be changed in the RabbitMQ configuration.

Possible drawbacks

There are no limitations introduced by this change.

Nice! thanks a lot for your contribution @alborzjafari

LGTM, but I've just seen there is no default_queue_type in the rabbitmq.conf file we are generating. I think is worth to add default_queue_type feature in both places:

• For the virtual hosts as you have done here.
• For the node with default_queue_type in the rabbitmq.conf.

Probably you have more context than me about that rabbitmq feature, could you add the last part? if not, there is no problem, I am happy to accept this PR as it is right now.

Thanks a lot for the feedback! 🙌
You're right — good point about default_queue_type in rabbitmq.conf. I've added that in the second commit. Let me know if there's anything else you'd like adjusted!
