This implements the same functionality as the former run.sh, but in Go and with a little better awareness of tailscaled's lifecycle. Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had where it would unconditionally try to reauth every time if you gave it an authkey, rather than try to use it only if auth is actually needed. This makes it a bit nicer to deploy these containers in automation, since you don't have to run the container once, then go and edit its definition to remove authkeys.
