Added support for multiple indices in open/close index apis

Open/Close index api supports now multiple indices the same way as the delete index api works. The only exception is when dealing with all indices: it's required to explicitly use _all or a pattern that identifies all the indices, not just an empty array of indices. Supports the ignore_missing param too.
Added also a new flag action.disable_close_all_indices (default false) to disable closing all indices

Closes #3217
