Support DogStatsD style tags in statsd-emitter (#6605) * Replace StatsD client library The [Datadog package][1] is a StatsD compatible drop-in replacement for the client library, but it seems to be [better maintained][2] and has support for Datadog DogStatsD specific features, which will be made use of in a subsequent commit. The `count`, `time`, and `gauge` methods are actually exactly compatible with the previous library and the modifications shouldn't be required, but EasyMock seems to have a hard time dealing with the variable arguments added by the DogStatsD library and causes tests to fail if no arguments are provided for the last String vararg. Passing an empty array fixes the test failures. [1]: https://github.com/DataDog/java-dogstatsd-client [2]: https://github.com/tim-group/java-statsd-client/issues/37#issuecomment-248698856 * Retain dimension key information for StatsD metrics This doesn't change behavior, but allows separating dimensions from the metric name in subsequent commits. There is a possible order change for values from `dimsBuilder.build().values()`, but from the tests it looks like it doesn't affect actual behavior and the order of user dimensions is also retained. * Support DogStatsD style tags in statsd-emitter Datadog [doesn't support name-encoded dimensions and uses a concept of _tags_ instead.][1] This change allows Datadog users to send the metrics without having to encode the various dimensions in the metric names. This enables building graphs and monitors with and without aggregation across various dimensions from the same data. As tests in this commit verify, the behavior remains the same for users who don't enable the `druid.emitter.statsd.dogstatsd` configuration flag. [1]: https://www.datadoghq.com/blog/the-power-of-tagged-metrics/#tags-decouple-collection-and-reporting * Disable convertRange behavior for DogStatsD users DogStatsD, unlike regular StatsD, supports floating-point values, so this behavior is unnecessary. It would be possible to still support `convertRange`, even with `dogstatsd` enabled, but that would mean that people using the default mapping would have some of the gauges unnecessarily converted. `time` is in milliseconds and doesn't support floating-point values.
