indexing changes for OSM ploys

I wish I'd done a better job of breaking this commit up, it represents a few things

- Make a separate table for polygons with object ids, put the oids on geocode records, lookup at the end
- with a 'mapping' file, do polygon conflation at runtime
- as soon as we read a polygon, start s2-indexing it in the background
- break up OutputHFile into multiple classes in output/
- run most indexers in parallel
- do more inserts in bulk to mongo for performance
- put index creation in code, rather than init-database, do it when needed so we don't pay the insertion cost for indexes
- add a mode to put genomes into namespace 0 for simplicity

man, I really wish these classes weren't such codependent spaghetti (mostly the increasingly poor separation by directly accessing the *DAOs

I wish for a lot of things. peace on earth and goodwill towards man, too.
