traced_probes: Add ProcessStatsDataSource
ProcessStatsDataSource should be able to write metadata for processes
which are created while a trace is running. To do this it needs to live
as long as the trace does so this change creates a
ProcessStatsDataSource to mirror the Sink and InodeFileMapDataSource
that exist for the ftrace and inode datasources.
This also pulls ProcessStatsDataSource and associated logic into its
own class: ProbesProducer is getting too big. Finally it adds the
boilerplate for testing ProcessStatsDataSource - but no actual tests.
There is some additional work required to add tests (e.g. creating a
fake TraceWriter impl) and that shouldn't block progress on
ProcessStatsDataSource.
