Add helper script to consolidate go stacktraces
Add helper script to consolidate go stacktraces

When we report deadlocks the stacktraces can be log and difficult to
follow. This scripts consolidates them, ignoring addresses, goroutine
IDs and goroutine age. The consolidated list of unique stacks (printed
with how often they occurred) are simpler to understand to find
deadlocks.
