1) Added new params for filtering by: - source share - usage of snapshot* - limit and offset a la pagination - direction (asc, desc)* - key of snapshot* * requires server-side update 2) Added aliases for params, mostly in perspective to avoid mess of underscore and dash symbols. Implements blueprint improve-snapshot-list-filtering Change-Id: I3727911f179ea01dd4cb68149fa7f4d79ca75a5c
