Asias He 4f77dd058d repair: Add tablet repair progress report support ...

This patch adds tablet repair progress report support so that the user
could use the /task_manager/task_status API to query the progress.

In order to support this, a new system table is introduced to record the
user request related info, i.e, start of the request and end of the
request.

The progress is accurate when tablet split or merge happens in the
middle of the request, since the tokens of the tablet are recorded when
the request is started and when repair of each tablet is finished. The
original tablet repair is considered as finished when the finished
ranges cover the original tablet token ranges.

After this patch, the /task_manager/task_status API will report correct
progress_total and progress_completed.
