The heat waitcondition signal API accepts status, reason, data and id
fields in a JSON object supplied as POST data. Missing fields will be
filled with defaults. Previously, the swarm script fragments used a
capitalised form of these keys (Status, Reason, Data, Id) which was
not being recognised by heat. This caused failures to not be reported.
This change uses the correct lowercase names for these fields and also
fixes some quoting and incorrect use of UUIDs provided as the id field.
