The Catalog model is unmanaged, meaning no corresponding table exists in the database. When dumpdata tries to dump this model, it chokes because there's no table to read from.

This now correctly migrates and dumps files for both databases.

Run lettuce migrations for both databases

This is a clone (copy) of CSMH's declaration and methods with an added
id of UnsignedBigInAutoField

We should be able to delete the save_history code, but needs testing.

Add error logging when capa failures happen

Put StudentModuleHistory into its own database

Bump out the primary key on CSMHE

This gives us a gap to backfill as needed.
Since the new table's pk is an unsigned bigint, even for people who don't
consolidate CSMH into CSMHE, the lost rows are unlikely to matter.

Remove StudentModuleHistory cleaner

It also contains the lettuce caches.

This will ensure a clean database for new runs, and will likewise
allow for the serversonly / testsonly approach for developing
bok-choy acceptance tests. The cleaner model will completely
rebuild the edxtest database for any new test run. This will
not be a costly maneuver because of our test cache.

Some mysql debian packages do not grant mysql user as many permissions, and
we need to add them.

There is a bootstrapping case where the test DB doesn't exist which causes reset_db to fail.
