[WFLY-1278] Upgrade HornetQ to 2.3.0.Final
upgrade metadata to latest version.
Upgrade EE7 APIs (CDI API, Interceptors 1.2 API)
AS7-6558 Initial CDI 1.1 support (Merged Weld 2 subsystem from https://github.com/weld/as7-weld-subsystem)
Added workaround for http://java.net/jira/browse/JAVASERVERFACES-2837
fix intermittent failures

leave some time after HornetQ server is activated before checking its
resources.
do the same after the :reload operation to avoid a false positive if the
server has not changed its server-state from running.

We had some failures in our integration server because the test was
checking a queue after the server activation while the queue was
installing (and not ready to handle a :read-attribute operation).
AS7-6790 Multi-JSF doesn't understand new modules structure.
WFLY-521 Initial EE7 mail support

- update javamail to 1.5
- support for @MailSessionDefinition & @MailSessionDefinitions
- support for definition of mail session via xml
