> Currently RegionServerServices has the following API:
> {code}
>   WAL getWAL(HRegionInfo regionInfo) throws IOException;
> {code}
> Caller can only obtain filenum for a specific WAL.
> When multi wal is in use, we should add API for obtaining highest file number among all
the outstanding WAL files.
> User can pass null to getWAL() method above, but the filenum for the returned WAL may
not be the highest among all the WAL files.
> See log snippet in the first comment.
