    Write user parameters environment to swift

    Currently we only merge this into the local merged environment,
    but instead we should write it as a separate user-environment in
    swift, which will enable heat server side parameter merging to
    work in future. The _write_user_environment function is added to
    handle writing the file to the local tmpdir tht_root, and uploading
    the same data to the plan.
