[Openstack-operators] Adding network node (Neutron agents) and test before deploying customer resource

I'm looking for the way to test a newly added network node by deploying test
resource before any customer resource on the node is deployed. I've learned
in this ML that Nova and Cinder has the setting of "enable_new_services" in
each conf to disable the initial service status to archive this.


My question is "Is there any function/configuration to do same thing for

I know there is on-going bug fix to implement the function to block
scheduling for Neutron agent[1].

As mentioned here [2], this fix may enable only administrators deploy
routers/dhcp-servers for test rather than having customer's one.

However, the initial "admin_state_up" status of agent still remains "true"
right after the agent or node is added.

That means it still happens the customer routers/dhcp-servers are deployed
the node before changing the status by manual.

To resolve this, I believe a feature similar to "enable_new_services" of
Nova/Cinder should be implemented to Neutron to change initial
"admin_state_up" value.

Do you know any existing function, blueprint or other approach to achieve
same goal?

Or, Is this the feature what you agree to want and should be proposed as a
new blueprint? 

I'd like to have neutron operators comments and suggestions.
