cluster/clustercfg: rewrite it in Go

This replaces the old clustercfg script with a brand spanking new
mostly-equivalent Go reimplementation. But it's not exactly the same,
here are the differences:

 1. No cluster deployment logic anymore - we expect everyone to use ops/
    machine at this point.
 2. All certs/keys are Ed25519 and do not expire by default - but
    support for short-lived certificates is there, and is actually more
    generic and reusable. Currently it's only used for admincreds.
 3. Speaking of admincreds: the new admincreds automatically figure out
    your username.
 4. admincreds also doesn't shell out to kubectl anymore, and doesn't
    override your default context. The generated creds can live
    peacefully alongside your normal prodaccess creds.
 5. gencerts (the new nodestrap without deployment support) now
    automatically generates certs for all nodes, based on local Nix
    modules in ops/.
 6. No secretstore support. This will be changed once we rebuild
    secretstore in Go. For now users are expected to manually run
    secretstore sync on cluster/secrets.
