utils.execute. This patch attempts to deal with the error
by mocking out Popen.communicate altogether.

Currently if an admin tries to create a trusted queue, Neutron will
fail with MissingDSCPForTrusted exception. However, the NVP semantic
is exactly the opposite, namely the DSCP field must be specified for
untrusted queues and omitted trusted ones.
