AWS doesn't install openmpi and mpich by default, this is added to replicate the other cloud providers.
This has been removed as it is a depulication of the mpi installation role.
The slurm install provided with this repo doesn't work with the default openmpi installed as it raises a pmix error. This does not occur on the epel supported slurm install.
In the epel repo libpmi is pmi.

Openmpi didn't work with the slurm repo used as it caused openmpi not to install correctly leading to a pmix error.
This pull request removes the need for an external repo for slurm and increases the slurm version number to 20.11. As well as unifying the openmpi and mpich installation, such that it is installed as default on AWS compute instances, like the other cloud providers.
