CLOUDSTACK-8733: Host stuck in rebalancing state during agent LB
This is happening as ClusterServiceServletAdapter is started after 
ClusteredAgentManagerImpl.
Fix is to start ClusterServiceServletAdapter before ClusteredAgentManagerImpl.

> During agent LB, sometimes host may get stuck in rebalancing state due to the 
> following failure in the rebalance process. This may happen if 
> ClusterServiceServletAdapter (which starts the listener on port 9090 and 
> processes agent LB related commands) is configured and started after 
> ClusteredAgentManagerImpl (which initiates the agent LB process).
