1. Test link quality based on packet loss & latency w.r.t. pre-defined high and low watermark values.
2. Extended ubus support to provide packet loss & latency information per wan per track_ip

Add a new ACTIONs:
* connected ACTION is called once if mwan3track reach all configured track_ips
* disconnected ACTION is called once if mwan3track is unable to reach the track_ips
The connected/disconnected will called only by mwan3track in opposite
the ACTIONs ifup/ifdown will also be called by netifd.

In some situation it is not enough to send a SIGTERM to mwan3track to
ask service to stop accurate. If this does not work send him a SIGKILL
to prevent mwan3track running more then once per interface.

If the date is changed by ntp the age value of mwan3 on ubus could jitter.
Use instead the uptime value from /proc/uptime which will not change during
system run.

If enough tracking ip are pinged skip the reset. They are not needed
anymore to mark the interface as up.

Fixes the following bugs introduced in commit 815e83d4:
- hotplug: invalid parameter order when initial interface state is "online",
mwan3track expects initial state to be the third argument
- hotplug: missing source ip address when initial interface state is "offline"
- mwan3track: source ip address should be the fourth argument

To know how old the ubus output is, add an age parameter which indicats
how old the check informations on the interface are.

Add new interface config option "inital_state".
If interface comeing up the first time(mwan3 start, boot),
there are now two option for interface behaviour:
- online (default as is now)
Set up interface regardless wether tracking ip are reachable or not.
- offline
Set up interface first to ping tracking ip and if they are reachable set up
the interface completely.

If two interface have the same prefix "wan" for example "wan" and "wan1"
pgrep returns the PID for wan1 also "pgrep -f mwan3track wan".
Before this fix "wan1" was also killed! This is not what we want.

Adds support for interface tracking using either ping, arping or
httping. This allows to track interface status on networks with filtered
ICMP traffic or simply to monitor data link layer etc.
To facilitate binding to a specified interface its IP address is passed
as a new mwan3track parameter. It's currently required by httping
and possibly by other tools that may be added in the future.

If mwan3track will not stop immediately after sending the kill signal,
the clean_up handler will delete the pid file later while the new mwan3track is
already running.
This could result in a situation that mwan3track is running
more then once because the old mwan3track service could not be killed,
because the pid file is missing.
Using pgrep to kill all mwan3track for the tracked interface and not using
pid file should fix this issue.

If interface is getting down by netifd (unplug ethernet cable)
mwan3track will not recognize this change. It will also generate an
additional down event when he notice does his tracking interface is offline.
Mwan3track will now be informed by a signal (trap) USR1 during down event
that the interface is already down. An additional down event will not be
generated.

If mwan3track detects a failure the interval check will change to
"failure_interval" value until this interface is declared "offline".
After interface gets "offline" normal "interval" value is used again.
If interface ping is successful again "recovery_interval" value is used until
interface is declared "online" again.
Using the different intervals will accelerate the wan line detections on
failure and recovery.
