Get package information based on Azure SDK for .NET names (Azure#2204)

* Get package information based on Azure SDK for .NET names

* Reset variables

With a `foreach` expression, variables never went out of scope and were never reset automatically. Need to do so manually.
Also filters on "azure*" for package names.
