Fixed #19115 -- Documented stdout/stderr options for call_command

      from django.core import management

      management.call_command('flush', verbosity=0, interactive=False)

      management.call_command('loaddata', 'test_data', verbosity=0)

Output redirection

==================

Note that you can redirect standard output and error streams as all commands

support the ``stdout`` and ``stderr`` options. For example, you could write::

    with open('/tmp/command_output') as f:

        management.call_command('dumpdata', stdout=f)
