This is a beauty we could have TripleO as official project.
However, this is solution by management.
We should have an architecture for supporting this resource management.

I believe existing situation is "Resource management happen inside the
individual projects instead of
in projects dedicated to working well in this space".
Neutron and nova has db table related with 'host'. (scheduler, agents)
TripleO/Tushar has a resource management table (
I don't know detail of the project, so please correct me if I were wrong here)
Nova-scheduler monitors compute nodes, neutron also monitors agents.
It looks like TripleO/Tushar is planning to monitor nodes.

My original proposal won't change config api, so this won't happen.
