> Goal: if counter's are used, there is no need to start counter's caches!
> Main change:
> * remove {{__counter_configuration}} and use the {{state-cache}} to store counter's configuration
> Summary:
> * When the first counter is defined and stored in the {{state-cache}}, the {{__counter}} cache is started. 
> * When a node joins, it starts the {{__counter}} cache if it finds a counter's configured stored
> * We need to persist the counter's configuration (for persisted counters only!) manually since the {{state-cache}} isn't persisted
> Issues
> * the {{state-cache}} is available during partitions! same counter can be defined with different configuration :( 
> users have to deal with it while I can't find a way to resolve a conflict.
