Yueh-Hsuan Chiang	bf287b76e0	Add structures for exposing thread events and operations. Summary: Add structures for exposing events and operations. Event describes high-level action about a thread such as doing compaciton or doing flush, while an operation describes lower-level action of a thread such as reading / writing a SST table, waiting for mutex. Events and operations are designed to be independent. One thread would typically involve in one event and one operation. Code instrument will be in a separate diff.

Summary:
Add structures for exposing events and operations.  Event describes
high-level action about a thread such as doing compaciton or
doing flush, while an operation describes lower-level action
of a thread such as reading / writing a SST table, waiting for
mutex.  Events and operations are designed to be independent.
One thread would typically involve in one event and one operation.

Code instrument will be in a separate diff.
