* Fix typo: _DEFALT_OP_NAME
* Extract ES document ID from URL, put in attributes
Elasticsearch creates URLs for index() and delete() before they hit
perform_request(). This means there would be many unique span names
containing unique document IDs, of the form
'Elasticsearch/indexname/_doc/documentid'.
This extracts the document ID from the URL and replaces it with ':id',
then puts it in the span's attributes.

matrix.
