Title: add choice 'service_and_name' for 'tag_for' option

This pull-req enhances `tag_for` option to add 'service_and_name'.
It is very useful for these points.

* it could use service name from tag and graph name together.
* on embedding image at external page, it is user friendly for including service name in the image.
