keep a running tally of consecutive number of successful or failed builds

This CL adds a google-storage backed streak counter, which counts the
number of consecutive passed or failed builds for each commit queue
builder. This is done by extending the functionality of GSCounter, and
adding a step to ReportStage which updates the gs-backed counter.
