There is no reason to read a single SSTable at a time from the staging
directory. Moving SSTables from staging directory essentially involves
scanning input SSTables and creating new SSTables (albeit in a different
directory).
We have a mechanism that does that: compactions. In a follow up patch, I
will introduce a new specialization of compaction that moves SSTables
from staging (potentially compacting them if there are plenty).
In preparation for that, some signatures have to be changed and the
view_updating_consumer has to be more compaction friendly. Meaning:
- Operating with an sstable vector
- taking a table reference, not a database
Because this code is a bit fragile and the reviewer set is fundamentally
different from anything compaction related, I am sending this separately

staging: potentially read many SSTables at the same time
