Add new Azure regions and allow user to select VM size (#332)

* Update Azure Region List

Included several additional regions in the Azure list.

In a future version we may want to ask users to choose a continent, then present region options since this list is getting long.

* Add VM size selection

Added prompt for user to choose VM size. Useful because the default size is not available in all regions, and there are cheaper sizes.

* Handle vm_size choice in "Create an Instance" step

Use the variable passed in that the user chose for vm_size.

* Differentiate Basic A0 and Standard A0

* Remove vm_size D1 since it's being deprecated

* Fix syntax issue - missing semicolons

* Remove note to self comment

* Remove changes to let user select VM size

Removing my previous additions that let the user select their Azure VM size.

* Hard code VM size to cheapest size

Remove my usage of a variable for VM size. Update to use the Basic_A0, which is the cheapest size of VM.
