Mehdi Abaakouk 6f9e46ba5c oslo.messaging context must be a dict 
oslo.messaging assumes the context is a dict not a RequestContext
and it assumes the payload in json serializable.

This patch ensures this.

Also it removes oslo.messaging mock on some tests and use real oslo.messaging
library with the fake driver.
