Also log unique request ID in HAProxy logs - LP:1895255

We need to use the capture request header to log the generated ID if
it exists in X-Cache-Request-ID. log-format replaces option httplog.

the caching layer enough so it's a 1-to-1 mapping of connections to
the caching layer through to backend.
