Currently, requestid field in logEntry is not populated, as the requestid field gets set at the very end. It is now set before regular handler functions. This is also useful in setting it as part of the XML error response. Travis build for ppc64le has been quite inconsistent and stays queued for most of the time. Removing this build as part of Travis.yml for the time being.
