Neutron is implementing tag support for network resource [0].
The implementation follows 'Tags' guideline defined by API-WG [1].
I have a questions on the guideline.


We can create a tag by PUT'ing an individual tag:
What status code should be returned if a requested tag already exists?

PUT /servers/1234567890/tags/qux

The guideline defines 201 (+ Location header) on success.
In the current neutron implementation proposed, 409 is returned
when a requested tag already exists.
