title: How to set priority in task in django-background-tasks?
body: <p>I run django web in development mode in windows powershell on windows server. I had some issues to make different tasks with different priorities, and run them in parallel instead of one by one.</p>
  
  <ol>
  <li><p>Tried to include "priority=1" in @background, it reported errors about no such parameters.
  @background(schedule=0, queue='1-qc-queue', priority=1)</p></li>
  <li><p>I even run two queue like "1-queue" and "2-queue" in two windows powershell
  "python manage.py process_tasks --queue 1-queue"
  "python manage.py process_tasks --queue 2-queue"</p></li>
  </ol>
  
  <p>but I saw all tasks are always with "priority=0" in background tasks table.</p>
  
  <ol start="3">
  <li>Tried to run multiple tasks in parallel:
  BACKGROUND_TASK_RUN_ASYNC = True
  but window powershell quit immediately</li>
  </ol>
