Code Issues Proposed changes

Fix clearing of the fake RPC Exchange

Browse Source 
The current fake driver does not properly clean up the fake RPC exchange
between tests.

This means that if a test invokes code that makes an RPC request, using
the fake driver, without consuming the RPC message, then another test
may receive this request making it fail.

This issues has been found while working on a Cinder patch and has been
worked-arounded there with Change-Id
I52ee4b345b0a4b262e330a9a89552cd216eafdbe.

This patch fixes the source of the problem by clearing the exchange
class dictionary in the FakeExchangeManager during the FakeDriver
cleanup.
