Subject [jira] Issue Comment Edited: (AMQ-1112) remove expired messages from Store and update Message cursors

r791881
Added a new expireMessagesPeriod (default 30 seconds) periodic task on a queue that iterates
though maxExpirePageSize(default 400) queued messages (or draws them into memory) to implement
deterministic message expiry. Can be disabled by setting expireMessagesPeriod==0 through a
PolicyEntry. A producer with no consumer will not longer be blocked on memory limits if a
message expiry is configured on a message as they will be actively expired every 30 seconds.
There is an additional expiredCount attribute in the destination statistics to track the count
of expired messages.
