CI lacks tests for the database drivers

[Michael Jones]

The CI lacks any automated tests to ensure the database drivers work correctly.

Comprehensive testing would involve (but isn't limited to):

1. Setting up a database using the turnserver's setup code for the DBDriver in question,
2. triggering an operation on each of the dbdriver interface's functions using the customary mechanism to trigger that
3. Also validating the operation with direct DB reads.

Wrenches that need to be thrown include:

( each of the below apply separately to each DB operation listed in the interface struct )

• Manually setup the DB, with intentional problems, such as an invalid schema or an insane number of rows of data
• Changing the DB during the operation of the server and ensuring the server picks up the new values in the way expected --
• Injecting values into the DB that are intended to break parsing code that is not properly defensive
• Sending data to the turnserver that will result in the data being fed into queries with the goal of performing sql injection attacks.
