    Do not drop all wheels with venv_rebuild

    Removal of venv_build_host_wheel_path leads to all wheels for all
    services being dropped which results in other role brokeness
    since we build wheels only when requirements or constraints
    file is changed. Also we technically don't need to clean it up, since
    removal of just rest of the files will lead to wheels being rebuild.

    This change should make usage venv_rebuild safe and not breaking wheels
    for all services rather then single one.
