ArtemisMQ version 2.18 Management API "rate" field

[foo bar]

Hello,

We use the core management API to administer ArtemisMQ. In version 2.15,
the "listQueues" operation on ActiveMQServerControl would return a json
with fields such as id, name, address, messageCount, consumerCount, and
rate to name a few. In version 2.18, "rate" is no longer being returned
(not in JSON) - is this on purpose or is this a known issue? Furthermore,
when using the web UI, I don't believe the "rate" column is being populated
if selected for display.

Thanks
