    Fix Qpid when sending long messages (from oslo)

    This is commit 4f97479ad 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.

    The first part of this fix was ported to Grizzly in Ib52e9458a to allow
    receiving messages from Havana using the new format. 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
