[WFCORE-100] Upgrade JBoss Log Manager from 1.5.2.Final to 2.0.0.Beta1

The first commit simply upgrades the log-manager to 2.0.0.Beta1 which contains some fixes and changes needed for WFCORE-101. There was also a license update from LGPL to Apache License 2.0.

The upgrade also added some new features to the SyslogHandler specifically around reconnecting a broken TCP socket. The audit log handles it's own reconnection and requires the use of a deprecated constructor for the org.jboss.logmanager.handlers.TcpOutputStream so no attempt to reconnect will be made. This is fixed by the second commit.

The third commit is included with this PR as it requires the upgrade to work and I have an open EAP PR pending on this change :)
