Band-aid for pip dependency bug
    
    pip install foo foo[more] does not install the extra dependencies 'more'
    of foo. It's a known bug in pip, see
    https://github.com/pypa/pip/issues/4391#issuecomment-290712930 and
    https://github.com/pypa/pip/issues/988
    
    The same bug applies to pip wheel. As a workaround pip wheel first
    builds extra dependencies, then wheel dependencies. This ensures that
    ipaclient[otptoken_yubikey] dependencies get built properly.
