Modules fix

* Dynamically download Az module (#29)

* Dynamically download Az module

Pre-baking of Az modules in runners will be refactored such that:
1. Only 1 latest Az module will be available as folder
2. Some high usage module versions will be available as zip based on platform
3. Other versions dynamically downloaded from Azure/az-ps-module-versions repo's releases
4. PSGallery will act as a fallback in case download fail from github releases

So to load the correct module from correct source the changes are done.
