It's the directory that owns the components lister and can reason about the way to pick up dangling bits, be it local directories or entries from the ownership table. First thing to do is to move the g.c. code into sstable_directory. While at it -- convert ssting dir into fs::path dir and switch logger. Signed-off-by: Pavel Emelyanov <xemul@scylladb.com>
