This is meant to be a one-time run, when setting up a new cassandra
cluster for page views and you want to migrate all your current page
views sitting in your db to that cluster.
test plan: generate some db page views, then switch configuration to
cassandra page views. run rake db:migrate_pageviews_to_cassandra and the
existing db page views should now be in cassandra, including showing up
in the user's page view history.

Adds a new back-end store for page_views, using a Cassandra cluster. All
the current page view queries are supported, many using denormalized
views on the data.
test plan:
first, canvas instances that are currently using AR page views
should function as before.
by Setting.set('enable_page_views', 'cassandra') and restarting, you will
switch to cassandra page views. a script to migrate the AR page views to
Cassandra is coming. all page view functionality should work as before.
note that the format of the pagination headers in the
/api/v1/users/X/page_views endpoint has changed.
