Edward Hennis 4702c8b591 Improve online_delete configuration and DB tuning: ...

* Document delete_batch, back_off_milliseconds, age_threshold_seconds.
* Convert those time values to chrono types.
* Fix bug that ignored age_threshold_seconds.
* Add a "recovery buffer" to the config that gives the node a chance to
  recover before aborting online delete.
* Add begin/end log messages around the SQL queries.
* Add a new configuration section: [sqlite] to allow tuning the sqlite
  database operations. Ignored on full/large history servers.
* Update documentation of [node_db] and [sqlite] in the
  rippled-example.cfg file.
