Version Differences for Server, Agent, and Relay Certificates

(Simple addition)
(cleaned up the fragment a little bit)
Line 1:
- The server needs the cert of the relay, the relay needs the cert of the server and the agents and the agents need the cert of the relay.   + If you have a situation where both SSL & Mutual Authentication are enabled between server <-> agents <-> relay, you will need to ensure the keystores & certificates are in the correct location. Otherwise you will receive error messages about certificates being invalid, certificates unknown, keystore tampered with, etc. The overall outline is listed below:  
       
    + * The server needs the cert of the relay  
    + * The relay needs the cert of the server  
    + * The agents need the cert of the relay
