    Tighten up how we add and remove kernel modules

    This change adjusts our two roles that configure kernel modules.
    These two roles serve slightly different purposes so they both
    must exist at this time. The change being made will ensure that
    the system module-load service is in reloaded anytime modules
    change, and that the `/etc/modules-load.d` directory exists
    before assuming we can write new configuration files there.

    > Molecule configuration for the tripleo-module-load role has
      been updated to ensure the role is functionally testing the
      code paths with real system values.
