[gold] Speed up and fix CL indexing

The big changes here are:
 - Avoid O(n^2) inside a loop (digest counter).
 - Do not fail silently on primary branch index and make
   sure we finish indexing the primary branch before
   computing CL indexes.
 - Modify tests so we cover the CL diff code.
 - Add environment variable to populate podName in tracing.
