+1 It looks good ; As a side note for koji we will need to have a 
permission that match the SIG ; the default permission for building is 
"build".

What we proposed is to have build-<signame> (build-cloud, build-nfv, 
build-virt ...) so we can match groups between FAS and Koji.

Now I don't think we want finer grained permission to project level e.g 
: build-<signame>-<project> (build-cloud-openstack) as everybody in a 
SIG should be trusted to do the right thing, however if there is some 
use case let us know.

This will be transparent to users, and add an extra security bit (no 
cross SIG errors) but we will need to sync FAS groups with Koji 
users/permissions.
