Route corresponding to VIP added by IPaddr2(or keepalived or ...) is left after VIP is removed

Issue

When VIP is added to an interface controlled by NetworkManager containing a DHCP supplied primary address, after the next DHCP renewal a static route is added for the VIP. That static route is not removed when the VIP is removed using iproute tools.
