We want to calculate bucket tally only from iterating objects.
Object currently has an info about totals for bytes and segments.
We need to adjust tallies to keep those totals. Older entries will
be untouched and code will use totals only if available. Change
is adding columns for totals to bucket_storage_tally table and
is adding general handling for them.
Next step is to start using total columns instead of inline/remote.
This will be done with next change.
