This PR proposes a CPU - only build of exawind (GPU containers to follow).

Build

podman-hpc build --no-cache -t <TAG_NAME> -f Dockerfile-containercpu .

Run

 podman-hpc run --rm -it <TAG_NAME>

After exiting a container, you will need to build the container again using a new tag name.

*Nota bene: * Docker can be used instead of podman-hpc

Concerns around this build include rather dated Trilinos (13.4.0) and Spack (ee68baf254ce8f401704ef1a62b77057487d4a12) versions.
