title: How: django_manage in ansible with Python3
body: <p>I'm following this for django manage.py module 
  <a href="http://docs.ansible.com/django_manage_module.html">http://docs.ansible.com/django_manage_module.html</a></p>
  
  <p>for e.g. one of my tasks  looks like -</p>
  
  <pre><code>- name: Django migrate
    django_manage: command=migrate
                   app_path={{app_path}}
                   settings={{django_settings}}
    tags:
      - django
  </code></pre>
  
  <p>this works perfectly fine with python2(default in ubuntu) but when I try with python3-django project it throws error</p>
  
  <pre><code>failed: [123.456.200.000] =&gt; (item=school) =&gt; {"cmd": "python manage.py makemigrations --noinput school --settings=myproj.settings.production", "failed": true, "item": "school", "path": "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games", "state": "absent", "syspath": ["/home/ubuntu/.ansible/tmp/ansible-tmp-1432039779.41-30449122707918", "/usr/lib/python2.7", "/usr/lib/python2.7/plat-x86_64-linux-gnu", "/usr/lib/python2.7/lib-tk", "/usr/lib/python2.7/lib-old", "/usr/lib/python2.7/lib-dynload", "/usr/local/lib/python2.7/dist-packages", "/usr/lib/python2.7/dist-packages"]}
  msg: 
  :stderr: Traceback (most recent call last):
    File "manage.py", line 8, in &lt;module&gt;
      from django.core.management import execute_from_command_line
  ImportError: No module named django.core.management
  </code></pre>
  
  <p>from this error it seems Ansible bydefault uses Python2. can we change this to python3 or anyother workaround?</p>
  
  <p>PS: pip freeze ensure that django 1.8 has installed (for python3 using pip3)</p>
  
  <p>Suggestions:
  when I run <code>ubuntu@ubuntu:/srv/myproj$ python3 manage.py migrate</code> it works fine. so I'm thinking of passing command directly
  something like </p>
  
  <pre><code> - name: Django migrate
     command: python3 manage.py migrate
     tags:
       - django
  </code></pre>
  
  <p>but how do I pass the project path or manage.py file's path, there is only an option to pass settings, something like  <code>--settings=myproject.settings.main</code>.</p>
  
  <p>can we do by passing direct command?</p>
