Michael Andre Pearce f63f130407 ARTEMIS-1235 delete queues when broker.xml changes 
Add extra configuration to address-settings to be able to
control / enable address/queue deletion by pattern,
rather than a global toggle.

Add support in the reload logic to remove address
and/or queues if the address matches an address setting,
where it is enabled.

Configuration Reload

The system will perform a periodic check on the configuration files, configured by configuration-file-refresh-period, with the default at 5000, in milliseconds.

Once the configuration file is changed (broker.xml) the following modules will be reloaded automatically:

  • Address Settings
  • Security Settings
  • Diverts
  • Addresses & queues

Notice:

Deletion of Address's and Queue's, not auto created is controlled by Address Settings

  • config-delete-addresses

    • OFF (DEFAULT) - will not remove upon config reload.
    • FORCE - will remove the address and its queues upon config reload, even if messages remains, losing the messages in the address & queues.

  • config-delete-queues

    • OFF (DEFAULT) - will not remove upon config reload.
    • FORCE - will remove the queue upon config reload, even if messages remains, losing the messages in the queue.

By default both settings are OFF as such address & queues won't be removed upon reload, given the risk of losing messages.

When OFF You may execute explicit CLI or Management operations to remove address & queues.
