Create DistributedWorkManager implementation based on WF clustering API

The upgrade to JGroups 4.0 will break the JGroups DistributedWorkManager implementation in IronJacamar (which uses JGroups 3.x). JGroups is only used to broadcast/receive commands to the cluster. This can be easily implemented using the WildFly clustering API. Such an implementation will simplify the transition to JGroups 4.0 and future-proof WildFly from any new API breakage.

Additionally, the JGroupsTransport in ironjacamar has some issues:

• Performs blocking operations on view change
• Does a lot of unnecessary serialization of Address
• Doesn't leverage multicasts
