commit 496ed6f1b279dc5ca560dec0044c8373531565f4
Author: Jarek Potiuk <[email protected]>
AuthorDate: Fri Jul 17 10:30:56 2020 +0200

    Reorganizing of CI tests (#9654)
    
    * we come back to idea of having one CI workflow
    * cancel and openapi are incorporated into that CI workflow
    * cancel retrieves workflow id automatically (works for forks)
    * static checks are now merged into one job
    * less dependencies between jobs so that waiting is minimised
    * better name for check if tests should be run
    * separated out script for tests should be run check
