    Debian: only update routes after interfaces are configured

    In Debian it was detected a dependency to create interfaces before
    the creation of routes. This change sets this order for the Debian
    installations, and keeps the current order for CentOS.

    Detected that is all static routes are removed the file
    /var/run/network-scripts/routes is not generated, we need to
    remove all route in /etc/network/routes. This was not happening

    Also adding log messages if the route creation/delete fails.

    Test Plan
    PASS add routes with system host-route-add and unlock on Debian
    PASS del routes with system host-route-delete and unlock on Debian
