Based on the Rocky spec [1] which says:

"instead we will resolve the cell database issue by running console 
proxies per cell instead of global to a deployment, such that the cell 
database is local to the console proxy"

Yes it's per-cell. There was stuff in the Rock release notes about this 
[2] and a lot of confusion around the deprecation of the 
nova-consoleauth service for which Mel knows the details, but it looks 
like we really should have something documented about this too, here [3] 
and/or here [4].
