In this PR I added compatibility with [statsd
protocol](https://github.com/b/statsd_spec) with tags to be able to send
metrics directly from statsd clients to vmagent or directly to VM.
For example its compatible with
[statsd-instrument](https://github.com/Shopify/statsd-instrument) and
[dogstatsd-ruby](https://github.com/DataDog/dogstatsd-ruby) gems
