KUDU-2353 (part 1): add a tool to parse stacks from diagnostics log

The diagnostics log uses a compressed format for storing stack traces.
While it's textual it's not really in a format that's amenable to human
consumption.

This patch adds a 'kudu diagnose parse_stacks' tool which takes a
diagnostics log and outputs a human-readable text format of all the
stack samples from the log.
