Title: Force create only, update is optional

Here is the change which makes `es-reindexer` more convenient for live index migration. Create only default prevents overwriting documents which already exist in destination. E.g. these can be new documents just added to new index by clients where re-indexation of old data from old index is in progress. Destructive update mode can be enabled by `-u` parameter.
