ap: Rearrange overloaded jobs
    
    With some recent changes the Azure Agent has decreased performance.
    For example, `InstallDNSSECFirst_1_to_5` (5 subjobs) job took ~33min
    and now it takes ~40min. In the same time there are jobs having only
    1 or 2 subjobs and they should be used more.
