Title: Configure Cross-Datacenter Replication (Remote Client-Server Mode)

Describe the issue:
Step
3. Configure Local Site Transport
shows a transport element which cause errors during server start. The attribute "cluster" is deprecated and if used which "LON" a NumberFormatException is thrown

Suggestions for improvement:
Clarification needed whether the attributes "udp", "cluster" and "executor" are necessary for some use-case.
Delete that part if it is not used.
Note that the example menitoned within the chapter does not contain it!
