Add a hotplug script to reload nlbwmon's config after interface
ifup actions.
That should improve the detection of the IPv6 LAN address
that can get enabled a bit later in the boot process.

(cherry picked from commit 5e140462e4)
Not all interfaces may have been allocated address at nlbwmon startup so
it may not collect statistics as expected/configured.
Add interface triggers to catch dhcp events and restart as required.

This commit introduces nlbwmon, the lightweight NetLink BandWidth Montor.
The nlbwmon daemon gathers per-host traffic statistics by querying netlink
accounting data. Due to this approach, the executable is very small and does
not rely on libpcap and CPU intensive raw sockets to monitor traffic.
Besides raw per-host traffic counters, nlbwmon also support rudimentary
traffic classification by observing IP protocols and used port numbers.
Gathered accounting data is stored into a series of database files which
are regularily committed to persistent storage.
Refresh, commit and accounting intervals are freely configurable as well
as the layer7 protocol mapping rules and observed source subnets.
This package also bundles a cli client which can be used to dump the
gathered traffic data as JSON, CSV or plaintext data. A pull request to
add a graphical LuCI frontend for nlbwmon is pending.
