Django 1.8 migration changes for xqueue

Now that XQueue's repo is running on 1.8, we need to use the new syntax
https://docs.djangoproject.com/en/1.8/ref/django-admin/#syncdb

This runs from the local machine and needs to know an IP of any member
of the cluster as well as the replica set.  We can add both of those to
the shim db/edxapp-mongo.yml file in the secure directories easily.

Use Django 1.8 migration command when updating ORA2.
