Accessing sample data (like period) for trace events from python scripts

Hey all,

It doesn't seem to be possible to access the period, tid and various other 
sample fields from a python (and perl?) script using `perf script`. My use-
case would be analyzing a perf data file created by perf inject --sched-stat.

I have hacked something together locally in python_process_tracepoint, but 
wonder what an upstreamable version should look like:

- I simply added the sample data to the dict, like is done in 
python_process_general_event

- Alternatively, one could think of more `common_period(context)` functions. 
If that is preferable, I could add the sample to the scripting_context and 
make that work.

Please advise the path forward, I'm willing to send a patch upstream to make 
it work.

Cheers
