This one is pretty obscure

There are a couple of issues with third party plugin migrations we need to solve here:

1. https://github.com/aldryn/aldryn-video/blob/</a><a class="double-link" href="https://github.com/okfn/website/commit/<a class="double-link" href="https://github.com/okfn/website/commit/126580c04fc6c0c60d23361280d56bd5333f5c51">126580c04</a>">126580c04</a><a href="https://github.com/okfn/website/commit/1ff532c7c30a3415aa8b1d393d237941f8a9c048">/aldryn_video/migrations/0001_initial.py#L11-L12
   depends on `__latest__`
   (which is essentially bug in most cases for this reason). Having already
   applied `aldryn_video 0001` now means we can&#39;t apply `cms 0016`
   the `temp_migration_settings` file allows us to temporarily un-register
   `aldryn_video` by running
   `python manage.py migrate cms 0016 --settings foundation.temp_migration_settings`
   without either breaking the site or failing on
   `django.db.migrations.exceptions.InconsistentMigrationHistory: Migration aldryn_video.0001_initial is applied before its dependency cms.0016_auto_20160608_1535 on database &#39;default&#39;.`
2. Some other migration relies on `easy_thumbnails 0001` but doesn&#39;t declare
   it as a migration dependency, so we need to run
   `python manage.py migrate easy_thumbnails` to avoid throwing
   `django.db.utils.ProgrammingError: relation &quot;easy_thumbnails_source&quot; does not exist`
3. Once we&#39;ve done those we can run `python manage.py migrate`
   to apply the remaining issues without error

Once we&#39;ve run this once on staging and once on production to migrate
the existing DBs correctly, we can do another commit to revert this change
and delete `temp_migration_settings`
and set CMD back to
`python manage.py migrate &amp;&amp; python manage.py update_index && /usr/bin/supervisord`
before the next deploy.
