Retry on requests error

Browse Source 
Added RETRY_ON_ERROR var. If its value is true, we'll try to get proper result MAX_RETRIES times, with RETRY_TIMEOUT delay between requests. Last request will be called outside of the try block, so it will throw an exception on failure

P.S.
I'm actually not sure if there are better ways to solve this problem, but this was my way of solving it
