Not directly related to this, but coincidentally we were talking about a 
bug in nova related to deleting compute nodes which reminded me of this fix:

https://review.openstack.org/#/c/406627/

And the bug for it, and the fact you have to manually delete compute 
nodes from the nova database, but you can delete the nova-compute 
service via the os-hypervisors REST API.

While working on that bug I pointed out the need for a nova-manage 
command or something similar to remove a compute node record from the 
database, which would also have to build in some checks to make sure 
that's safe, but the point is, this is a need we have in nova itself, so 
it'd be sweet if someone was willing to work on adding that command to 
nova, rather than have lots of random similar scripts in different tools 
repos.
