Allow bulk actions to have routing

The elasticsearch bulk API allows for each item to have a routing value
which helps prevent bulk actions from being broadcast to all shards.

http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-bulk.html#bulk-routing
Allow the passing of a routing value for `deleteIds()`

If all ids to be deleted during a bulk API request are routed to the same
shard allow that routing value to be set so that the delete command is not
broadcast to all shards.
