WFLY-330 - Allow defining server http port (and other basic properties) via jvm arguments Obs: This is working, but the final tests on subsystem.xml fails because the final value is not int.

I change the ajp, http, https and remoting.
These parameteres can be configurated on Jvm Parameters like that:
-Djboss.http.port=9080
-Djboss.https.port=9843
-Djboss.remoting.port=4487
-Djboss.ajp.port=8010

If not set, the default is configurated.

This is work OK, but the surefire final test fails on:
org.jboss.as.test.smoke.subsystem.xml.StandardConfigsXMLValidationUnitTestCase

and

org.jboss.as.test.smoke.mgmt.BasicOperationsUnitTestCase

We need adjust the tests Too.
