Yes, actually I think most of the devtest_overcloud content fits 
os-cloud-config (and IIRC for this purpose os-cloud-config was created).

Well, the scope of this lib will be beyond configuration of a cloud so 
having "-config" in the name is not ideal. Based on feedback in this 
thread I tend to go ahead with os-cloud-management and unless someone 
rises an objection here now, I'll ask infra team what is the process of 
adding the lib to stackforge.
