I have a -1 on the change, will state the same reason here. Without a 
cap on oslo.utils in stable/liberty g-r, this will break at least nova 
in stable/liberty since it's a backward incompatible change.

As with most things now, I think the path forward is getting nova onto 
the new code, raise the min required version of oslo.utils in mitaka to 
where the new methods were added (that's probably already the case if 
the deprecation happened awhile ago), and then the deprecated functions 
can't be removed until liberty-eol.
