At present, the address-setting expiry-delay allows setting a TTL if message has not already set it.

However, when using the broker in a service offering, being able to enforce a TTL range for messages regardless of message TTL is necessary.

Example:

<address-setting match="myqueue">
  <min-expiry-delay>10</min-expiry-delay>
  <max-expiry-delay>100</max-expiry-delay>
</address-setting>

TTL of messages without TTL will be set to max-expiry-delay
TTL of messages with TTL above max-expiry-delay will be set to max-expiry-delay
TTL of messages with TTL below min-expiry-delay will be set to min-expiry-delay
TTL of messages with TTL within min-expiry-delay and max-expiry-delay range will not be changed
