Subject: [PATCH] support ignored globs & limit in file search & plugin-ext

- in current Theia, passing "ignored globs" or "limit" to plugins-api from plugins does not work, as the data is dropped before reaching the file search service. This change ensures the data goes through and handled by the service.
