title: Clearing history while debugging azure durable functions
body: <p>Durable functions keep a state in storage, this is what makes them work, but it is very troublesome while debugging and developing. I have a large number of runs which have not completed and that the system tries to run again when I start the process. Some of the runs have erroneous data same which causes exceptions while others have been terminated early as something did not work as expected.</p>
  
  <p>I don't want to run all the old cases when starting my application in debug (running against my local storage account). How can I automatically clear all data so only new functions will trigger?</p>
