Open Stack

Hi everyone

Found that Heat doesn't keep the value of X-OpenStack-Request-ID header
during request processing. Simple stack delete leads to 4 different request
id, only the last of them corresponds to heat engine processing the
request. Investigation shows that req-id "duplicates" twice - when client
goes via redirect response returned by API and at version negotiation at
every connect to API endpoint. I assume that this situation is not
expected, and it really spoils work with heat api logs. Any ideas on how to
make the situation more clear?

Also looks like that header name is case-dependent in some places, and
Oslo-middleware and Heat handles them differently. However, it needs
additional investigation.

I propose to turn off logging for successful negotiation and re-use req-id
in keystoneuth during redirect. If it is ok, I plan to submit
corresponding patches to upstream.

Here is a piece of log related to stack delete. Only "req-843ac3a4..."
exists in the heat-engine log.
