Subject: hosts/carmel: reconfigure the host as a router

I'm not using it as a desktop, and the current router is getting old and
will likely fail in the near future. It's also a debian machine
configured manually, so let's reconfigure carmel as our new router.

There are three NICs in the host: 2 are 10Gb and one is 1Gb. The 1Gb
will be used as the upstream interface, and one of the 10Gb will be for
the LAN.

There are 2 VLANs to configure: one for IoT devices and one for guest.
