Update dockerhub to match README

[asmacdo]

Using dockerhub readme I couldn't get the cluster to start.

README (Works great, thanks!): docker run -it -h slurmctl --cap-add sys_admin giovtorres/docker-centos7-slurm:latest

Dockerhub (Failure output below): docker run -it -h ernie giovtorres/docker-centos7-slurm:latest

This fails, I suppose the hostname must be slurmctl.

Updated! Thank you. I haven't done a good job at keeping the integration up to date.

I see it adjusted, e.g. so I guess could be closed (by @giovtorres or @asmacdo -- I have no powers)
