Remove all oauth tokens + consumers (on test env)


I have a clone of our production setup right now and upgraded that setup to kong 2.0.1.
How can i easily remove all consumers + added oauth keys/clients & basic auth to the consumer?

I need to move the cassandra cluster, last time i did it i spent 2 days on moving it because we have a lot of tokens / Consumers created.

A CQL query to drop all the rows in the oauth2 tables would be the fastest way.
