[LibreQoS] network.json and ShapedDevices.csv for Multi-Wan SOHO

The fastest way to get support is via the #libreqos:matrix.org
chatroom, although we also do github bugs and good ole fashioned
email.

So wonderful to see you trying it. Are you using v1.3, v1.4-rc2 or the
heimdall (v1.5) branch?

It doesn't sound to me as though you need much of a network.json. A
flat topology will suffice, unless you need to model multiple devices
further down the chain from VLAN_X.

As for the upstream though, load balancing that is kind of painful and
more the domain of pfsense than libre.

Additionally, shaping those upstreams properly is problematic, I would
probably use pfsenses's native fq_codel implementation on each of
those WAN interfaces to install an upper limit for egress but on
ingress... hmm... and in either case something needs to attempt to
direct the "right" amount of traffic through those interfaces.
