Part of the API refactor; this introduces a gRPC server for ntp. This allows the ability to query node time and check time against specific ntp servers. This refactor also moves the ntp functionality into a sub package for better project organization. Signed-off-by: Brad Beam <brad.beam@talos-systems.com>
