Abstract DatadogStatsClient to ForemStatsClient (#12304)

* This change abstracts the DatadogStatsClient into a ForemStatsClient.
The purpose of this abstraction is to set the foundation for a subsequent PR that will allow one to use New Relic for recording Forem stats, instead of Datadog, if there is a New Relic configuration found.
This specific change creates an abstraction layer that can be built upon, without changing any actual default behavior. All specs still pass.

* Use delegate instead of explicit methods.

* Delegate instead of explicit methods.

* Fix the error.

* Refactor according to the suggestions in the comments.

* Ooops.  Stats work better when all of the code is committed.

* Removing the alias of count to increment since that was done in error.
