Title: add post-replace hook dropping all udp streams

When default route changing, all tcp connections resets, but udp streams remains.
It leads to udp related network services try to send packages on old, dead gateway and application not working. For example, asterisk affected to this trouble.
The solution is drop all udp streams using conntrack.
