Pull Request conventions

• All threads have to be resolved before merging
  • A thread is resolved by a Reviewer , not the Assignee
  • An issue should be created and related information including the issue should be added as a comment if a thread should not be worked on as part of the PR
• Assignee and Reviewer clearly indicate to the other when their work is done
  • This should be done with e.g. 🏓 @NAME for all the changes
  • Procedural: The Reviewer can leave a thread to be closed by the Assignee with a 🎩

Optional:

• An Approve shall be given with 🚀 @NAME
