veyron/tools/debug: Add debug command-line tool
This change adds a command-line tool to interact with the debug server
that's built into all IPC servers. We can access log files, inspect
stats, and run pprof.
$ export NAMESPACE_ROOT=/proxy.envyor.com:8101
$ ./debug glob tunnel/hostname/rpi001/__debug/*
tunnel/hostname/rpi001/__debug/logs
tunnel/hostname/rpi001/__debug/pprof
tunnel/hostname/rpi001/__debug/stats
$ ./debug glob tunnel/hostname/rpi001/__debug/logs/*INFO
tunnel/hostname/rpi001/__debug/logs/tunneld.INFO
$ ./debug logs read tunnel/hostname/rpi001/__debug/logs/tunneld.INFO
[...]
$ ./debug pprof run tunnel/hostname/rpi001/__debug/pprof heap -text
[...]
$ ./debug stats watchglob tunnel/hostname/rpi001/__debug/stats/...
[...]
etc.
