    Openswan/Libreswan: Check config changes before restart
    
    Currently, when neutron-vpn-agent restart, all the pluto process in
    router ns will be restarted too. But actually this is not required
    and will impact the vpn traffic. In this patch, we keep a backup for
    ipsec.conf and ipsec.secrets, and then compare the configurations
    when restart, if no config changes. Restart can be skipped.
    
    Note: this change is DocImpact
