    Fix problem with long messages in Qpid (from oslo)

    This is commit 478ac3a3e in oslo-incubator

    Qpid has a limitation where it cannot serialize a dict containing a
    string greater than 65535 characters. This change alters the Qpid
    implementation to JSON encode the dict before sending it, but only if
    Qpid would fail to serialize it. This maintains as much backward
    compatibility as possible, though long messages will still fail if they
    are sent to an older receiver.

    Even though this change will modify the message format, it will only do
    it when messages are longer than 65K which would be broken anyway and
    could cause serious bugs like the one linked below.

    Fixes bug 1215091
