(dsccommunity#567) Fix CICD

CICD in Azure Devops appears to be broken.

Adding all of the features under `Web-Server` was breaking in
Server 2019 core, was not capable of easily adding the .NET3.5 features.
It turned out that those features were not required so they were
dropped in favor of a more granular set of features for that image.

SSL downloads from the technet gallery were broken in the unit tests
due to incorrect TLS protocol.

The `win1803` server core image and the Windows 2012r2 image
`vs2015-win2012r2` are both being dropped from Azure Devops Pipelines
and have both been replaced in this commit by `vs2017-win2016` as per
Microsofts recommendation at https://devblogs.microsoft.com/devops/removing-older-images-in-azure-pipelines-hosted-pools/
