Yueh-Hsuan Chiang d0c5f28a5c Introduce GetThreadList API 
Summary:
Add GetThreadList API, which allows developer to track the
status of each process.  Currently, calling GetThreadList will
only get the list of background threads in RocksDB with their
thread-id and thread-type (priority) set.  Will add more support
on this in the later diffs.

ThreadStatus currently has the following properties:

  // An unique ID for the thread.
  const uint64_t thread_id;

  // The type of the thread, it could be ROCKSDB_HIGH_PRIORITY,
  // ROCKSDB_LOW_PRIORITY, and USER_THREAD
  const ThreadType thread_type;

  // The name of the DB instance where the thread is currently
  // involved with.  It would be set to empty string if the thread
  // does not involve in any DB operation.
  const std::string db_name;

  // The name of the column family where the thread is currently
  // It would be set to empty string if the thread does not involve
  // in any column family.
  const std::string cf_name;

  // The event that the current thread is involved.
  // It would be set to empty string if the information about event
  // is not currently available.

Test Plan:
./thread_list_test
export ROCKSDB_TESTS=GetThreadList
./db_test
