Brad Davidson c51d7bfbd1 Add health-check support to loadbalancer
* Adds support for health-checking loadbalancer servers. If a
  health-check fails when dialing, all existing connections to the
  server will be closed.
* Wires up a remotedialer tunnel connectivity check as the health check
  for supervisor/apiserver connections.
* Wires up a simple ping request to the supervisor port as the health
  check for etcd connections.

Brad Davidson c87e6e5f7e Move proxy dialer out of init() and fix crash
* Fixes issue where proxy support only honored server address via K3S_URL, not CLI or config.
* Fixes crash when agent proxy is enabled, but proxy env vars do not return a proxy URL for the server address (server URL is in NO_PROXY list).
* Adds tests
