[Openstack] [metering] Ceilometer High Availability

Is there a session focused on HA and distributed collection at the 
summit? As we have been discussing in a separate thread, we (HP) have 
been approaching this in terms of configuration management, but the real 
requirement is to be able to distribute collection at runtime to support 
scalability and HA. Our current collector (pre-ceilometer) looks at its 
configuration at runtime to determine if its primary and which sources 
it needs to collect from. This allows us to run multiple instances of 
collection in parallel with synchronization. We will need the same 
capabilities from ceilometer.
