Allow dropping light client RPC query with no results (#9318) * OnDemand no longer loop until there is a query. All peer known at the time will be queried, and the query fail if all return no reply. Returning the failure is done through an empty Vec of reply (the type of the oneshot channel remains unchanged). Before this commit the query were send randomly to any peer until there is a reply (for a query that got no result it was an issue, for other queries it was quering multiple times the same peers). After this commit the first query is random but next queries follows hashmap iterator order. Test no_capability was broken by this commit (the pending query was removed). * OnDemand no longer loop until there is a query. All peer known at the time will be queried, and the query fail if all return no reply. Returning the failure is done through an empty Vec of reply (the type of the oneshot channel remains unchanged). Before this commit the query were send randomly to any peer until there is a reply (for a query that got no result it was an issue, for other queries it was quering multiple times the same peers). After this commit the first query is random but next queries follows hashmap iterator order. Test no_capability was broken by this commit (the pending query was removed). If adding some kind of timeout mechanism it could be restored. * Comment plus better field names. * No panick on dropped oneshot channel. * Use Set to avoid counter heuristic * Cli option `on_demand_nb_retry` for maximum number of retry when doing on demand query in light client. * Missing test update for previous commit * Add a timeout (only when there is no peer to query), that way we do not set number of query to minimum current number peer or configured number of query : that way capability test was restored. * Adding an error type for on_demand, it helps having variant of error reported at rpc level : choice of rpc error code error might not be right. * Duration as constant is nice * Switch to duration in main too * Fix indentation (sorry for that). * Fix error management (bad merge in previous commit) * Lots of english corrections, major change on the new command parameters : - use standard '-' instead of '_' - renaming nb_retry params to 'on-demand-retry-count'
