Possibility to define retry count to session

[patrijuh]

We are using this library over not 100% stable network connection. Packets get lost sometimes without reaching the destination leading to timeouts leading to our TA builds to fail on random. Possibility to define retry count and interval would be really valuable to us. These do exists in python request library, so could similar be implemented to this library?
