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 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.

On interfaces with interface proto "qmi|ncm" and option dhcp
enabled the interface will be changed to $iface_4 | $iface_6. The
interface mapping in mwan3 will not recognize this interface. To fix
this issue an ubus call will check if an upper interface exists.
