After a node is scaled down to a target node, the sf queue in the
target node is not deleted.
Normally this is fine because may be reused when the scaled down
node is back up.
However in cloud environment many drainer pods can be created and
then shutdown in order to drain the messages to a live node (pod).
Each drainer pod will have a different node-id. Over time the sf
queues in the target broker node grows and those sf queues are
no longer reused.
Although use can use management API/console to manually delete
them, it would be nice to have an option to automatically delete
those sf queue/address resources after scale down.
In this PR it added a boolean configuration parameter called
cleanup-sf-queue to scale down policy so that if the parameter
is "true" the broker will send a message to the
target broker signalling that the SF queue is no longer
needed and should be deleted.
If the parameter is not defined (default) or is "false"
the scale down won't remove the sf queue.
* Upgrading versions
* Adding wildfly-common dependency as jboss-logmanager now depends on it
for simple common operations such as getting hostname or process id
* Updating bootclasspath with wildfly-common

Add fix - if timeout occurs on sending packet, calls same code that is invoked if timeout occurs on during ping aligning logic, and ensuring JMS connection exception listener gets invoked to inform the client logic to react.
Historically the broker has read the XML configuration file as a String,
substituted system properties, and then parsed that String into an XML
document. However, this method won't substitute system properties in the
files which are imported via xinclude. In order to substitue system
properties in xincluded files the substitution needs to be performed
after the file is parsed into an XML document. This commit implements
that change and refactors the XMLUtil class a bit to eliminate redundant
code, obsolete comments, etc.
Implement using the ActiveMQ5 JMSXGroupFirstForConsumer, property as default, but make it possible for future to make it configurable easily. (Not this PR)
Add test
In adding auto-delete queue level feature, its been noticed as some feature bits were added during hot fix branch, that there's api break with the 2.6.x hotfix branch.
This addresses that by fixing this in 2.7.x
