Release management

[mbhoek]

As an owner, I want to document (or even better: automate) the release process.

Currently in place:

• Squash merge feature branches into master
• Gitversion calculates SemVer (use +semver: commit message to influence)
• Azure DevOps Build
  • builds PRs and master
  • tests
  • creates NuGet package
  • publish package as artifact
• Azure DevOps Release
  • creates a draft GitHub release (needs manual editing)

As an owner, I want a single button to:

• [x] trigger the release automatically after approval
• [x] build, test and package the release
• [x] deploy the package to NuGet.org
  • note that NuGet takes time to verify a release
  • there are additional interesting fields to set, like the Release Notes
• [x] create a GitHub release
  • only after listed on NuGet.org

The only thing I skipped is "creating a GitHub release after pushing to NuGet". Upon further thought this didn't make sense (especially not at this stage of the project).

This issue is basically solved as of #9
