Add timeout to requests.post() in client

[Bpless]

Looks like you guys are not adding a timeout here. Seems like a nice way to degrade in the event that you service is down.

At the very least, offer it up as a configurable option.

The requests library allows you to specify a timeout as an optional keyword arg.

Thanks! just added a timeout thats default to 10 seconds: https://github.com/segmentio/analytics-python/blob/master/analytics/client.py#L67

you can set the timeout as a named argument in analytics.init(secret, timeout=20)
