Setup azure pipelines without VSTest.

#2049 was opened to setup azure pipelines but `VSTest` is hanging there. MS have been investigating but until that gets resolved all our PRs have a big red X next to them. This adds a working azure-pipelines.yml setup that skips tests but should allow builds to pass.
