[Feature request] Federated ASK/EXISTS queries sent to remote server

[MaillPierre]

Is your feature request related to a problem? Please describe. When I send a federated ASK query such as ASK { SERVICE { ?s ?p ?o } }, the Corese server sends the following query to the server:

select *  where {   ?s ?p ?o . } limit 1000

Describe the solution you'd like I would like to know if there is a setting to put the limit of the sent query to 1 or if federated ASK queries could be sent to the remote server as ASK sub-queries instead of a SELECT one.

Describe alternatives you've considered I can use the service extension feature, but it requires doing a lot of parsing/rewriting work on every query to automate the querying.
