WFLY-381 Add undertow support to mod_cluster subsystem.
HornetQ security manager doPrivileged() block

move all HornetQ user and roles validation into a single
AccessController.doPrivileged() block.
validateUserAndRole() is called from a thread in HornetQ own's thread
pool. Calling it inside  a doPrivileged() block ensures that the code
will not raise an AccessControlException when WildFlySecurityManager
checks the permissions.
Group all the doPrivileged blocks into a single one.
Surefire tests leave jdr_zip file because it cannot be deleted while open. Also move it to target/ and test outputDir/close.
[WFLY-1434] Enable assignment of groups for management users.

These groups will subsequently be used to assign role membership for domain management access control.
[WFLY-878] MDB DeliveryActive property

* update jboss-ejb3-ext-api version to 2.1.0
* add management operations start-delivery & stop-delivery
 (+ delivery-active runtime read-only attribute) to be able to
 start/stop delivery on the MDB resource (under
`/deployment=<deployment_name>/subsystem=ejb3/message-driven-bean=<mdb_name>`).
* by default, the MDB is started and delivery of messages occurs as soon
  as the MDB is deployed (no change from the previous behaviour)
* add support for jboss-ejb3-ext-api's @DeliveryActive to annotate the
  MDB or alternatively using the urn:delivery-active:1.0 element in
  jboss-ejb3.xml deployment descriptor
Make it possible for DeploymentProcessors to register additional AroundConstruct interceptors
WFLY-412 Add support for @AroundConstruct
WFLY-1426 wildfly-parent.pom: upgrade Jackson to 1.9.12 to be consistent with RESTEasy
[WFLY-1637] Also restrict permissions on additional property files used for authentication / authorization.

WFLY-529 CDI and Bean Validation integration for method validation

- Add a module for the Hibernate Validator CDI portable extension
- Replace the delegate of LazyValidatorFactory with the CDI-enabled ValidatorFactory provided by the CDI portable extension
Restore original module name for mod_cluster extension in default configuration files.
[WFLY-1599] Add support for mgmt-groups.properties, at the same time ensure groups and not roles are referenced.
WFLY-1632 Cannot deploy distributable application when is defined jdbc-store for web session
[WFLY-1635] Add a new map-groups-to-roles attribute to allow users to configure if there is a 1:1 mapping between the two.

If set to false (The new default) then no mapping occurs and at the time of authorization mapping is expected to occur dynamically.
[WFLY-1635] Minor changes to map-groups-to-roles model handling from review comments.
