[HAL-454] Add support for adding a periodic-size-rotating-file handler.

This is my first real PR for the console so please tell me if this is completely wrong :)

This is an attempt to add the new [```periodic-rotating-file-handler```](https://issues.jboss.org/browse/WFCORE-18). This was just merged upstream and is not in a release yet. I wasn't sure if the PR needed to wait for a release of WildFly Core and/or WildFly.

There is also an [EAP issue](https://issues.jboss.org/browse/EAP6-254) for this as well as a [pull request](https://github.com/jbossas/jboss-eap/pull/1532). This has not been merged yet.
