Add support to all other events in profile.py

Currently `profile.py` only support CPU cycles. It should support all other events where we see in `perf list`.

What would be the best user interface? Should we use the same event name string as `perf` or user would just specify event type / config directly?

Read profile.py and compare its CPU-cycle handling with the events exposed by perf list. Resolve whether the interface should accept perf event names or event type/configuration directly, then verify that the chosen interface supports the other perf events.
