Matrix Strategy (#111)

* Matrix Strategy

Adding a strategy to run in 3 regions : eastus, westus2, southcentralus

location parameter was never set in the 03 notebook but added azlocation to set that field when running that notebook.

* Re-order parameters

Papermill complained it didn't know abut azurerggroup, but similarly said it didn't know what estimators were....

* Correct Param Names

azurergname wasn't used throughout the matrix strategy, only the first one, which seems to make sense based on the results.
