title: Is there a way to know whether Tracer is success fully connected to jaeger backend server in jaegerclientcpp?
body: <p>In <code>jaeger-client-cpp</code> when I connect my <code>Tracer</code> variable to jaeger backend (I m using <code>jaeger-all-in-one</code> server) then upon successful connection <code>LOG INFO</code> message is shown telling me the connection is successful, but when connection is unsuccessful is just shows <code>LOG ERROR</code> message telling me that connection with server not successful.</p>
  <p>So is there any way to check this programatically about the status of connection of <code>Tracer</code> with server.</p>
  <p><code>OS-ubuntu 18.04</code>
  <code>jaeger-client-cpp-v0.5.0</code></p>
