Title: add option -i to ignore creating the destination index and only copy

We needed the ability to copy documents into a new index with different mappings. I added the -i option to disable creating the destination index assuming that this index is already created. When -i is passed it will only copy the documents from the source/index. This was used for reindexing when we needed to change the mappings.
