StatsdClient fails silently when there's no statsd listening on the given address

[gsalgado]

Neither CreateSocket() nor any of the metrics-generating methods (i.e. Timing(), Incr(), etc) return an error when there's no statsd listening on the address given when creating the client, as can be seen at the following gist: https://gist.github.com/gsalgado/07b8bec3e326582c7174

I'd expect them all to return an error in this case.

It's normal behaviour for UDP connections
