Bump production sqlite timeout from default of 5s to 20s.  Sqlite only allows one client at a time to have the database file open for writing, so in a larger environment clients can timeout waiting for a write lock. Since virtually all writes are made by clients registering their state there's no problem with them having to wait up to 20s to submit and this seems to be the wisdom of the Internet about how to use sqlite in production at scale.
