Flip blacklist for MySQL eventlogging consumer to be a whitelist of allowed schemas.
We continuously run into problems with MYSQL processor in eventlogging.
(example: https://phabricator.wikimedia.org/T203592)
Going forwards by default all events should go to hadoop and only a whitelist of events should appear on MYSQL, we can build whitelist by looking at the topics in kafka (eventlogging-valid-mixed) from which data to MySQL is persisted.
