Open Stack

Related to this change [1] which adds a new LIBERTY openstack version to 
the metadata service API, it's pretty trivial but it's akin to 
microversions in the nova-api v2.1 code, and we require blueprints and 
specs for those changes generally.

So do we require a blueprint and optionally a spec for this type of 
change, or is it simple enough as a bug fix on it's own?
