1) Added new params for filtering by: - share network - snapshot - volume type - host - limit and offset a la pagination - project id (useful with '--all-tenants') - metadata* - extra-specs* - direction (asc, desc)* - key of share* * requires server-side update 2) Added aliases for params, mostly in perspective to avoid mess of underscore and dash symbols. 3) Updated utils.print_list func to print results as is without reordering. Implements blueprint improve-share-list-filtering Change-Id: I6fe92c5242f18c900e109271f9182bd5ed287b25
