replace akka-app with kamon jvm metrics

[hntd187]

As per @velvia suggestion in gitter, I think kamon would be fantastic because it gives a lot of the tracing and such that we are looking for and I think with the context-per-jvm functionality we should definitely look to have this implemented there. It will also allow us to get rid of the old akka-app portion of the code.

With that in mind, I once many moons ago upgraded yammer metrics to drop wizard metrics, but that branch is my "break the world" branch so trying to take what I did out of it would probably be a horrible horrible rebase.

So here is my plan to accomplish this

1. Remove the akka-app from the current code
2. Implement all the old metrics using kamon
3. Ensure same functionality to our previous metrics
4. Implement the aspectj features where/if necessary as optional things for people to add as they see fit
5. Perhaps offer another artifact for those aspectj metrics
6. Maybe allow for custom metrics in spark jobs? (Perhaps functionality for the future)
7. ???
8. Profit!

I think 1-4 should be straight forward since I know already what I'm doing, the rest we should discuss.
