Have created a new Dockerfile for image creation to run containers on
CentOS 7 with GlusterFS 3.13 already installed.
Also sent a pull request on Github to merge a new branch named
gluster-3.13 with this new Dockerfile included.
Test on Centos 7 release 7.4.1708 (Core) with kernel
3.10.0-693.17.1.el7.x86_64 and works ok:
