disable / avoid urllib3 error output[enhancement] #152
Description
I wrote a script that grabs information about tickers on my computer at specific times. If I don't have wifi, there is a long error script from it, that I would like to disable. I can only catch your error, not any urllib3 ones. Output:
HTTPSConnectionPool(host='poloniex.com', port=443): Max retries exceeded with url: /public?command=returnTicker (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x101b64a58>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',))

I finally caught this error after all that was outputted:
HTTPSConnectionPool(host='poloniex.com', port=443): Max retries exceeded with url: /public?command=returnTicker (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x10279ddd8>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',))
How can I avoid / silence this?
