new 644cf3486d7 HBASE-28502 Cleanup old backup manifest logic (#5871)
644cf3486d7 is described below
commit 644cf3486d7085bdcbfceae170c55e47f129d534

HBASE-28502 Cleanup old backup manifest logic (#5871)
In older versions of HBase's backup mechanism, a manifest
was written per table being backed up. This was since refactored
to one manifest per backup, but the manifest code was not updated.
A concrete issue with the old code was that the manifest
for full backups did not correctly list the tables included
in the backup.
