* Allow cio_id to be used as the identifier on the path

If you want to update identifiers that are already set for a person, you must reference them using their cio_id in the format cio_<cio_id_value>; attempting to update identifier values for a person without referencing them by cio_id will result in an Attribute Update Failure.

* cio_id on the path needed prefix cio_

* allow events to use cio identifier

* fix: customer endpoints
