agent-compute doesn't log "x-openstack-request-id" that provided by nova-api's response

[Tatsuro Makita]

Issue:
Ceilometer-agent-compute has periodic task that is calling nova-api.

Ceilometer-agent-compute does not output "x-openstack-request-id" in ceilometer-agent-compute's log.
It's difficult to trace log between ceilometer-agent-compute and nova-api.

Below the log of ceilometer-agent-compute:
<pre>
REQ: curl -i 'http://192.168.243.222:8774/v2/6c231f4ea6754a26b4fe3b27c3e331f9/servers/detail?all_tenants=True&host=interdev3' -X GET -H "X-Auth-Project-Id: service" -H "User-Agent: python-novaclient" -H "Accept: application/json" -H "X-Auth-Token: 4e9ce4664cf447febc0bd9e714fb5b32"

</pre>

This problem, similar events have also occurred in periodic task of ceilometer-agent-central.

X-openstack-request-id is worthful functionality especially for the operator who's tracing problem's root cause.

We will be able to trace easily when ceilometer-agent-compute outputs "x-openstack-request-id" in the DEBUG log.
For example, "grep -r <x-openstack-request-id> /var/log/devstack"

want to switch this over to bug 1244182? i'm assuming their the same. if not, please continue :)

Hi Gordon. Thank you. watch my this report.
This report bug is little same bug 1244182.

I think that bug 1244182 is ceilometer's request-ids of report.
This bug is nova-api's request-id.

Please you watch my patch.
Please wait a little more because I try this patch up soon.

regards.

    Add log output of "x-openstack-request-id" from nova

    This patch enables ceilometer to output
    'x-openstack-request-id'/'x-compute-request-id'
    of nova's responses to the log.
    And it also enables ceilometer to output
    request headers, request parameters,
    other response headers and a response body to
    the log when ceilometer calls nova.

    DocImpact: There is a new configuration option
    'nova_http_log_debug' in ceilometer.nova_client
