[WFLY-4045] regression test for plain TCP used in auditLog-to-TLS-syslog handler

Regression test for TLS auditlog to syslog handler issue -  https://issues.jboss.org/browse/WFCORE-190

The issue caused for some TLS handler configurations only a plain TCP connection was used.

This test needs WFCORE update (i.e. version where the https://github.com/wildfly/wildfly-core/pull/257 is merged already).
