metropolis/metroctl: implement cluster configure

This is a framework for simple ClusterConfiguration changes via
metroctl. We only have one mutable field for now
(kubernetes.node_labels_to_synchronize), but more fields can be
supported later.

This could also be extended to support operations like 'add' and
'remove' for repeated fields.

Finally, there could be another CLI command that would drop you into a
prototext editor, similar to `kubectl edit xxx`. But this solves the
simplest usecase for now.

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).
  • A reasonably recent kernel with user namespaces enabled.
  • 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.
