Adds support to SSL on Wildfly

To try this image follow the build instructions or just run:

`docker run -it -p 8080:8080 -p 8443:8443 abstractj/wildfly:jboss`

Or just run:

`docker build -t jboss/wildfly .`

The readme instructions were updated, also.
@goldmann sure I'm ok if it. But I would like to see what would be the possible alternative to this change first https://github.com/jboss/dockerfiles/pull/27#discussion-diff-16703813R56
