[ Merge of http://go/wvgerrit/103395 ] To help with debugging failures in HTTP requests during unit tests, this CL adds logging for Google's debugging response header fields. These fields are of the type "X-Google-*" or "x-google-*" and provide information such as the service name, server cell, error details, and other details that can help isolate the cause of failure on the server's end. An additional unittest has been created to test the parser for the header fields. Tests that are known to exprience HTTP failures have been extended to include logs for these fields should they be present. Bug: 137619348 Test: Linux unit tests and Jenkins test Change-Id: I69959af2ba91510f345bbb02cf7ca35c3f1119da
