Doc Text:	Previously, the default value of the 'l3_ha' option was set to 'true' in all circumstances. This would cause deployments with a single controller to fail or exhibit errors such as "HANotEnoughAvailableAgents: Not enough l3 agents" when running neutron-related commands under certain conditions. With this update, the 'l3_ha' option is now automatically set to 'false' in deployments with a single controller, preventing neutron-related commands from failing due to this state.	Story Points:	---

Deploying with a single controller then trying to create a router results in error:
