Get rid of Timeout#timeout

This gets rid of the call to `timeout` when writing results to StatsD.  Using a timeout to write to a UDP socket does not make sense, given the stateless nature of UDP.  Also, Ruby timeouts are notoriously :shit:, as documented here, https://coderwall.com/p/1novga, for example.  This has manifested stuck background jobs in Shopify.

Also, calling `connect` on the UDP socket (though it doesn't really make sense) actually flows through a more optimal code path when calling `send`: https://github.com/ruby/ruby/blob/trunk/ext/socket/udpsocket.c#L167
