Support federated search across a set of Arvados clusters

|Velocity based estimate||-|
System administrator can configure a set of API servers which are part of a federation and which should be contacted to do federated searches.
Workbench uses that list to send search queries to each of the API servers in parallel and displays all search hits federation wide to the user.
Permissions are checked based on the user identity in the same way that they are today for a local user (so this depends on Federated Identity).
