Fix checkstyle
Avoid duplicated logic
Ability to filter and group
Instantiate SimpleString property key once
Get property value via getObjectProprty to ensure all special mapped properties such as in AMQPMessage would return
Avoid a custom string to represent null, instead rely on Java's representation "null" by using Objects.toString to get the string value of the property value used to group by.
Seperate plugin interface by area, all extending a base interface.
Update code to check and call only plugins implementing specific interfaces.
Existing interface extends all the new interfaces for back compatibility or those who want simplicity and don't care about perf.
An OpenWire client can use a compound destination name of the form
"a,b,c..." and consume from, or subscribe to, multiple destinations.
Such a compound destination only works for topics when the subscriber
is non-durable. Attempting to create a durable subscription on a
compound address will end up with an error.
The cause is when creating durable subs to multiple topics/addresses
the broker uses the same name to create internal queues, which
causes duplicate name conflict.
The LRUCache is not thread-safe and it's usage in SelectorParser could
cause growth beyond its configured max size. Instead of modifying the
LRUCache to be thread-safe or synchronizing access to it in
SelectorParser it should just be removed since it's not on a hot path.
The deliver loop won't give up trying to deliver messages when
back-pressure kicks in (credits and/or TCP) if msg grouping is used and
there are many consumers registered: this change will allow the loop
to exit by instructing the logic that the group consumer is the only
consumer to check.
Parameters going into Wait.waitFor were originally wrong, because
`durationMillis: 3, sleepMillis: 100` means you would test the condition
only once. This commit is changing the durationMillis from 3ms to 3s,
swapping the two numbers (duration 100ms, sleep 3ms) would also be reasonable, I think.
Next, Wait.assertEquals is here being used, instead of Assert.assertTrue.
I saw the test fail only once, and never was able to reproduce it again,
but I think this commit does improve the test and so it is worthwhile.

I did not observe the timing issue on all asserts (only on the first
two), but there is no harm in replacing them all.
