Remove the requireExplicitBindings from each of the individual modules and provide control for this option from the Bootstrap.

The default behaviour is to require explicit bindings. If the user wishes to disable the requirement for explicit bindings, during
the creation of the injector the user must knowingly turn off the check (*). This allows Airlift to work with systems like
Sisu (http://eclipse.org/sisu) which currently do not have 100% explicit bindings.

  public static void main(String[] args) throws Exception {
    Bootstrap app = new Bootstrap(
        new NodeModule(),
        new DiscoveryModule(),
        new HttpServerModule(),
        new JsonModule(),
        new JaxrsModule(),
        new MBeanModule(),
        new JmxModule(),
        new JmxHttpModule(),
        new JmxHttpRpcModule(),
        new LogJmxModule(),
        new HttpEventModule(),
        new TraceTokenModule(),
        new MainModule(),
        new WireModule(new MavenBehaviourModule(), new SpaceModule(space(), scanning()))
    );

    try {
      Injector injector = app.strictConfig()
          .requireExplicitBindings(false) // (*)
          .initialize();
      injector.getInstance(Announcer.class).start();
    } catch (Throwable e) {
      log.error(e);
      System.exit(1);
    }
  }

Fix connect timeout test on Linux

The server socket backlog is actually a hint and might be ignored
entirely. On Linux, the minimum backlog size is 16. So, we set the
minimum backlog and keep connecting until it fails with a timeout.
