Investigate use of EasyBuild for AToM components

[orso82]

ITER is using EasyBuild on their cluster to manage software: https://easybuild.readthedocs.io/en/latest/

I have not looked to much into it but the description of the EasyBuild project reads "a software build and installation framework that allows you to manage (scientific) software on High Performance Computing (HPC) systems in an efficient way."
which sounds promising

@kalling would you have some time to investigate if this could be a viable option for distributing AToM software. Perhaps as an alternative to SPACK?

Hopefully this is better than NotSoEasyBuild.

A while back I watched a presentation that covered some of the differences between Spack and Easybuild. At the time, It seemed like Spack was closer to what we wanted, but I will look at it again.
