veyron/runtimes/google/vtrace: Add capturing via regexps to vtrace.
This CL makes VTrace easier to use.
- Add a flag that specifies a regexp pattern so you can select
traces by span name or annotation.
- Turn dump_on_shutdown on by default.
Now you can run vtrace with just:
--veyron.vtrace.collect_regexp=.*
