Typically the sstable_directory is constructed out of a table object.
Some code, namely tests and schema-loader, don't have table at hand and
construct directory out of schema, sharder, path-to-sstables, etc. This
code doesn't work with any storage options other than local ones, so
there's no need (yet) to carry this argument over.
