title: How i can disable alembic logging at runtime?
body: <p>I need to disable alembic migrations logging, while executing migrations in unit tests, .</p>
  
  <p>I can't just remove <code>alembic</code> logger it from <code>alembic.ini</code>: i need this output while performing migrations myself.</p>
  
  <p>Following did not work for me:
  <code>logging.getLogger('alembic').setLevel(logging.CRITICAL)</code></p>
  
  <p>How i can disable it at runtime?</p>
