Create new instance of the master node of replicated storage. There are two kinds of replication slave nodes:
statically defined and dynamically added. First one are specified by replicationSlaveNodes parameter.
When replication master is started it tries to eastablish connection with all of the specified nodes.
It is expected that state of each such node is synchronized with state of the master node.
It is not possible to add or remove static replication slave node without stopping master node.
Dynamic slave nodes can be added at any moment of time. Replication master will send to such node complete
snapshot of the database.
