Add options to improve dogstatsd packet deliverability.
Description of the Change
Allow dogstatsd socket to be used in a blocking mode with a timeout. This improves our chances to send the packet if the socket queue is full (e.g. after a burst in packets).
Add a background thread to handle the writes, with a queue to act as a buffer.
Together, this allows users to reduce dropped packets to zero while maintaining low latency for the user application, at the cost of higher cpu and memory usage.
