m/n/core: simplify network overlay

During the initial refactor into the role server the node external IP
(which was then used as the underlay target) got moved into the
published prefixes. This never did anything as the summary route into
clusternet does not contain it. Thus drop this and simplify the code.

Also remove the extra loopback IP introduced in 011dce6623 as it never
worked because control plane nodes do not even have a prefix to pick
such an IP from.

While at it, rename some variables to make them more accurate with how
this is eventually going to look.

Monogon Monorepo

This is the main repository containing the source code for the Monogon Platform.

This is pre-release software - take a look, and check back later! In the meantime, join us on Matrix (#monogon-os-community:matrix.org) or Discord.

Environment

Our build environment is self-contained and requires only minimal host dependencies:

  • A Linux machine or VM.
  • Bazelisk >= v1.15.0 (or a working Nix environment).
  • git to check out modules.
  • python3 to generate the workspace status to stamp.
  • A reasonably recent kernel, user namespaces are recommended for performance reasons.
  • Working KVM with access to /dev/kvm (if you want to run tests).

Our docs assume that Bazelisk is available as bazel on your PATH.

Refer to SETUP.md for detailed instructions.

Monogon OS

The source code lives in //metropolis (Metropolis is the codename of Monogon OS).

See the //metropolis/README.md for a developer quick start guide, or see the Monogon OS Handbook for user documentation.
