Yueh-Hsuan Chiang 77a5a543a5 Allow GetThreadList() to report basic compaction operation properties.
Summary:
Now we're able to show more details about a compaction in
GetThreadList() :)

This patch allows GetThreadList() to report basic compaction
operation properties.  Basic compaction properties include:
    1. job id
    2. compaction input / output level
    3. compaction property flags (is_manual, is_deletion, .. etc)
    4. total input bytes
    5. the number of bytes has been read currently.
    6. the number of bytes has been written currently.

Flush operation properties will be done in a seperate diff.

Test Plan:
/db_bench --threads=30 --num=1000000 --benchmarks=fillrandom --thread_status_per_interval=1
