Set timeout of Analytics request

When there's redirect in the request, XMLHttpRequest doesn't handle it very well and the console hangs for 10 minutes.

EqatecMonitor.js call setTimeout of XMLHttpRequest with default value - 10000 ms. Add SetRequestTimeout method to EqatecMonitor which sets global timeout variable (currently this method is not used).

The timeout is required in order to prevent console hanging when analytics cannot send the request.
