* The federation layer on top of the search container. This contains

*
* - A model of Sources which can be selected in and for a Query and which are implemented
* by a Search Chain, and Providers which represents the connection to specific backends (these
* two are often 1-1 but not always)
*
- The federation searcher responsible for forking a query to multiple sources in parallel
*
- A simple searcher which can talk to other vespa services
