StatsD Tagging

[sjmtan]

This is somewhat a duplicate of #110.

I know that StatsD Reporter doesn't support tagging: https://github.com/uber-go/tally/blob/master/statsd/reporter.go#L151

I believe this is the case because the cactus/go-statsd-client didn't support tags until this year:

• https://github.com/cactus/go-statsd-client/issues/53
• https://github.com/cactus/go-statsd-client/releases/tag/v5.0.0

Can the statsd client be upgraded to support v5 and therefore support tags?

Hey guys, the PR was created 3 years ago, could you please finally merge this? It would be really great to finally have tags for the statsd reporter.
