Chained replicas

Current implementation of read-only replicas require them to be connected to the cluster. It means that every new replica adds some overhead to the operational cluster nodes, particularly its leader. It creates limitation of the feature as one mig...

Remove the PLUGINS__ configuration section

The users don't need to know or care whether what they are configuration is a plugin or not. e.g. Instead of EVENTSTORE__PLUGINS__AUTOSCAVENGE__ENABLED we could have EVENTSTORE__AUTOSCAVENGE__ENABLED The tradeoff (and the reason why it is like thi...
