[LibreQoS] adapting cake to the environment

[Dave Taht]

in seeing the complaints about other products bashing on snmp too
hard, it occurred to me that some of the
currently end-user focused work here:

Might actually also apply within an ISP to adjust the AP emulation in
libreqos based on these sorts of active measurements which require no
more than ping, or ntp messaging, to work.

I especially like the ability to use ICMP based type 13 messages which
makes it possible to calculate one way delays (OWD). There was some
branch that leveraged ntp also.
