[openstack-dev] [nova] Host maintenance notification

I have the following scenario. I have an application consisting of multiple VMs on different compute hosts. The admin puts one of the hosts into maintenance mode (nova-manage service disable ...) because there will  be some maintenance activity on that host in the near future. Is there a way to  get a notification from Nova when a host is put into maintenance mode?
If it is not the case today would the nova community support such an addition to Nova?

As a subsequent question is there a way for an external system to listen to such a notification published on the message bus? 

Thanks in advance.
