[azure pipelines] automatically attach artifact to releases

[Raffaello]

set up a CI that upload the artifacts (CPack) from the CI build.

Or generate the release from the CI, with tags.

there will be conflicts with app-veyor. so it should be choose one or the other.

• [x] create artifacts
• [x] set up the release in azure-pipelines
• [x] disable appveyor release (comment out)

more or less.

this get me worry:

How do I consume artifacts? Consume artifacts in release pipelines You can download artifacts produced by either a build pipeline (created in a classic editor) or a YAML pipeline (created through a YAML file) in a release pipeline and deploy them to the target of your choice. At present, you cannot download artifact produced by a YAML pipeline in another YAML pipeline.

done the release in the CI build filter the step by a tag present condition.

at the moment i prefer the generated release of appveyor. so i probably comment out the azure one and re enable the appveyor.
