correlation_id missing from http.audit.request/response events

[Matthew Edmonds]

The correlation_id trait is missing from http.audit.request and http.audit.response events when queried from ceilometer.

so this does not appear to be an easy fix... I thought we could just add this to the yaml, but does ceilometer support special processing for tags? They have a different structure than other things on the notification. E.g.:

    "tags": [
        "correlation_id?value=openstack:e612f987-a439-452b-a0a1-caaf2229dfb5"
    ],

vs.

    "observer": {
        "id": "target"
    },
    "outcome": "pending",

etc.

Per Gordon, answer to comment 1 is that we would probably have to build a plugin to parse it: https://github.com/openstack/ceilometer/blob/master/ceilometer/event/trait_plugins.py
