    Removed the default pip install options from upgrade.sh

    Instead of forcing to reinstall pip packages during an upgrade, we
    should instead make sure the environment always have the latest pip
    package version.

    This commit is part of a group of commits to ensure latest pip packages
    are installed in the venv (cf. topic pip-install-latest on gerrit) for
    the standard playbooks, and remove the options used by default in the
    upgrade script (pip_install_options=--force-reinstall)
