Description

KUDU-2297 added a diagnostics log which includes periodic metrics dumps as well as stack samples. We have a somewhat-crufty 'parse_metrics_log.py' script which no longer works with the new format, and was never particularly good anyway. We should add more tools baked into the 'kudu' CLI tool to parse the log and extract interesting information such as human-readable stack trace snapshots, metrics in TSV form, etc.
