    Fail early in case of error in env directory path

    Specified environment directories were silently ignored if they didn't
    exist, meaning a typo in a path argument might only be discovered very
    late, after the deployment finishes.

    The ~/.tripleo/environment special case is preserved, and will still be
    silently ignored when not present.
