Bug Description

If a connection fails, for example due to invalid authentication, several pyngus and proton objects create cyclic references. As connections are created/destroyed, these objects accumulate. Proton's SASL functionality starts to fail as the underlying SASL library fails to release resources.

    Fix a few leaks in the AMQP 1.0 driver.

    Break any references that can form a cyclic reference. Several of
    proton's python classes define __del__ methods, so a cyclic reference
    must be broken manually.
