We only sync the metadata and data in the runtime of blobstore, which
means we only update the used md bitmap and used clusters bitmap in memory.
if the system crushed, we have no chance to sync the used md bitmap and
used clusters bitmap into disk, then next time when we try to load the
blobstore, all the data will lost, this patch add the logic to recover the
valid data from last dirty shutdown. We will go through all the metadata pages
to find all valid data and rebuild them.
