Finish Hardening of profileBuilder

[marstr]

As seen here:
azure-sdk-for-go/tools/profileBuilder @ 8150bd

I have a program that will automatically create the necessary Go packages to support an Azure API Version profile. The previous version of this program was a prototype that took a text-based approach of generating profiles. Taking advantage of the AST, I was able to encapsulate the creation of an alias pretty well. That work can be found (for now at least) here: https://github.com/marstr/goalias.

The remaining work in the profileBuilder relates to automating the process of building a collection alias packages that will form a profile. Particularly, discovery of latest API Verisions to create a profile. Later, work will need to be done to support lists of API Versions.

This work is complete, and can be seen in #767.
