[openstack-dev] [dib][heat] dib-utils/dib-run-parts/dib v2 concern

While looking through the dib v2 changes after the feature branch was 
merged to master, I noticed this commit[1], which bring dib-run-parts 
back into dib itself.  Unfortunately I missed the original proposal to 
do this, but I have some concerns about the impact of this change.

Originally the split was done so that dib-run-parts and one of the 
os-*-config projects (looks like os-refresh-config) that depends on it 
could be included in a stock distro cloud image without pulling in all 
of dib.  Note that it is still present in the requirements of orc: 

Disk space in a distro cloud image is at a premium, so pulling in a 
project like diskimage-builder to get one script out of it was not 
acceptable, at least from what I was told at the time.

I believe this was done so a distro cloud image could be used with Heat 
out of the box, hence the heat tag on this message.  I don't know 
exactly what happened after we split out dib-utils, so I'm hoping 
someone can confirm whether this requirement still exists.  I think 
Steve was the one who made the original request.  There were a lot of 
Steves working on Heat at the time though, so it's possible I'm wrong. ;-)

Anyway, I don't know that anything is broken at the moment since I 
believe dib-run-parts was brought over unchanged, but the retirement of 
dib-utils was proposed in https://review.openstack.org/#/c/445617 and I 
would like to resolve this question before we do anything like that.
