id assignment

   How does this loadbalancer bookkeeping work once we get multiple Controllers 
in the mix? There's some extra shared state and coordination required when 
assigning and remembering the UUID to Invoker id mapping?
   
   If an Invoker dies, the only way to get an Invoker registered to that 
numerical Invoker id again is to use the proposedInvokerId? If I just start up 
a new Invoker without telling it which Invoker id to propose then it will get 
assigned a new topic in Kafka instead of draining from the orphaned one. So, in 
practice, my deployment tooling needs to keep up with Invoker ids just like it 
does today?
