(Attempt To) Create Integration Sample w/ Microsoft FASTER

[Microsoft FASTER](https://github.com/Microsoft/FASTER) is one edge technology we have on the to-look-at list in order to improve performance of certain workloads within Orleans. It's a young project and still in a rough shape but it shows very promising potential as a hybrid storage solution for large dictionary-style collections, especially if it gets at least a basic iteration story off the ground. I'm bound to build a prototype of this at some point, so I'm creating this issue here in case anyone wants to have a go at it in the mean time. Otherwise, feel free to assign this to me.
