m/{node,proto}: implement Node Labels

Nodes can now have Labels attached to them. These are string key/value
data designed after Kubernetes labels. They are meant to be used to
attach metadata to nodes, for example external IDs, nicknames or
geographical information.

This change implements just the core functionality: storing them within
etcd, retrieving them via management and curator APIs, and mutating them
via a new management RPC.

Followup changes will impelement provisioning labels at
bootstrap/registration time and accessing label data from metroctl.

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.

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.
