structured logging

[roadscape]

Currently hive indexer logging is basic console output, though tuned to produce useful output at the INFO level at a reasonable volume. Hive server logging could use some work. And generally there's a mix of prints and logger.getLogger, with hacks for other packages' noisy loggers (sa & jsonrpcserver). Hive's logging would benefit from a refactoring and polishing.

• [x] standard logging solution -- untangle logger config, or use other package?
• [ ] tune hive.server logging -- each request is logged; need to track errors but control spam
• [ ] json-based logging? (jg)

+100 for json based logging, that's what all new node.js services (conveyor, kingdom, gatekeeper, faucet, faucet-admin, overseer) uses already

scalyr auto-parses json logs as well
