Create containers for CI

[cedricchevalier19]

To speed up the CI, especially for GPU-enabled compilations, we can use an ad-hoc image.

Ideally, we need:

• GPU and non-GPU aware MPI (but it should be for tests once we have GPU runners)
• Different flavors of MPI implementations
• Different levels of MPI support: with and without MPI_Sessions, for example (Draft kokkos-comm initialization/finalization using MPI_Sessions #68)
