4974fc7c24 Use sync.WaitGroup to avoid exiting before components have shut down
Currently only waits on etcd and kine, as other components
are stateless and do not need to shut down cleanly.

Terminal but non-fatal errors now request shutdown via context
cancellation, instead of just logging a fatal error.

529e748ac7 Move apiserver ready wait into common channel
Splits server startup into prepare/start phases. Server's agent is now
started after server is prepared, but before it is started. This allows
us to properly bootstrap the executor before starting server components,
and use the executor to provide a shared channel to wait on apiserver
readiness.

This allows us to replace four separate callers of WaitForAPIServerReady
with reads from a common ready channel.

We are not making use of the stack traces that these functions capture, so we should avoid using them as unnecessary overhead.

ff679fb3ab Refactor supervisor listener startup and add metrics
* Refactor agent supervisor listener startup and authn/authz to use upstream
  auth delegators to perform for SubjectAccessReview for access to
  metrics.
* Convert spegel and pprof handlers over to new structure.
* Promote bind-address to agent flag to allow setting supervisor bind
  address for both agent and server.
* Promote enable-pprof to agent flag to allow profiling agents. Access
  to the pprof endpoint now requires client cert auth, similar to the
  spegel registry api endpoint.
* Add prometheus metrics handler.

992e64993d Add support for kubeadm token and client certificate auth
Allow bootstrapping with kubeadm bootstrap token strings or existing
Kubelet certs. This allows agents to join the cluster using kubeadm
bootstrap tokens, as created with the `k3s token create` command.

When the token expires or is deleted, agents can successfully restart by
authenticating with their kubelet certificate via node authentication.
If the token is gone and the node is deleted from the cluster, node auth
will fail and they will be prevented from rejoining the cluster until
provided with a valid token.

Servers still must be bootstrapped with the static cluster token, as
they will need to know it to decrypt the bootstrap data.

dc18ef2e51 Refactor log and reaper exec to omit MAINPID
Using MAINPID breaks systemd's exit detection, as it stops watching the
original pid, but is unable to watch the new pid as it is not a child
of systemd itself. The best we can do is just notify when execing the child
process.

We also need to consolidate forking into a sigle place so that we don't
end up with multiple levels of child processes if both redirecting log
output and reaping child processes.
