Perform a multitude of config changes

- Make all config class names singular
- Create caching repo's for all aggregates
- Set the repository for each aggregate through the annotation
- Add the two command publishing event handlers to a
'commandPublishingEventHandlers' processing group
- Add todo to CompanyConfig to move the snapshot trigger def bean to
another config file
- Remove all redundant declarations from the OrderConfig
- Change the buy/sell TradeSagas to be backed by a
TrackingEventProcessor
- Remove all redundant declarations from the UserConfig
