GET survey submissions, without presenting client id

[eric-jahn]

Necessary for management of survey collection process.

Example use case: sometimes management need to see the surveys collected the past day to match surveys incorrectly attributed to different client ids, when really the surveys were for the same actual person.

Other examples.

Not having this API call forces the client to cache recent surveys for this type of by date/recent grouping.

request parameters: search by date range or by survey submission count
paginated

wouldn't a search be better than GET? Then no need to GET them and cache them just to search them.
