[EXAMPLES] console_debug not working in otlp exporter examples.

[marcalff]

In file examples/otlp/http_main.cc:

    opts.url = argv[1];
    if (argc > 2)
    { 
      std::string debug  = argv[2]; 
      opts.console_debug = debug != "" && debug != "0" && debug != "no";
    }

Exporter options console_debug can be set optionally from the command line, which is a nice debug feature.

The problem is that this has no effect, because GlobalLogHandler::SetLogLevel() is never set to DEBUG.

Console logs are never printed.
