JBoss Middleware base layer

Note	Extends RHEL base image

This is a very minimalistic layer containing changes that are applicable to all Middleware images. The purpose of this layer is to provide ground base and enforce common settings for all Middleware images. This includes:

1. Updates to the OS

2. Creation of the jboss user (and group) with uid/gid 185 used to start every Middleware product process

3. Setting working directory for the image: /home/jboss

4. Switching to the newly created jboss user
