oracle-template: Split patching rootfs vs one time setup into separate shell functions so the template can be run with --patch. oracle-template: Update to install the yum plugin and itself (as lxc-patch) into a container. The plugin just runs lxc-patch --patch <path> so it is fairly generic, but in this case it is running a copy of the template inside the container.
