ARTEMIS-2504 implement retroactive addresses

re: "My original plan was to have the ring queues for the retroactive
address under the main address itself, but I didn't want those queues to be
subject to the address-settings of that address. Separating the ring queues
onto their own address means better configuration flexibility."
The issue here are
1) you have to message copy, not just make new references - expensive if you
have a large retro active to get through, also will cause paging faults to
occur as copies occur, even if consumer isnt at that message.
2) its going to be very messy as an end user to make address settings for
the internal's, especially as typically (as an end user, i probably just want
the same settings for bit like paging etc)
3) address settings do not update the queue (in general they are defaults,
overrides and actuals are always set at queue level), as such once queue is
created its not going to be possible to adjust
Also having it at the address allows us to, and the way i was seing this
working so then you can set this being better configurable and working nicely
is to have these defined as sepecial queues under the address (eg. in
broker.xml)
<address name="MyAddress">
<multicast>
<queue name="MyQueue" group-buckets="64"
group-rebalance="true">
<filter string="ServiceId = 1" />
<durable>true</durable>
</queue>
<retro-active-queue group-buckets="0" >
<message-count>1024</message-count>
</queue>
</multicast>
</address>
This way then it can expose any queue settings, easily.
