Scopes: Add Find subresource to query ScopesNodes and search thru titles.

[bergquist]

I want to add an API handler that can filter for scopenodes based on ParentName and also search for titles matching a keyword passed as query. AFAIK the query part is not something that the API server itself support which is why I'm adding a sub resource for it instead.

But I can't figure out how to query the apiserver from the handler.
