Separate cipher lists for instances acting as a client
Prior to this feature, the cipher list specified in the `server.xml` file was used when a Certificate System instance was acting as a server as well as a client. In some cases, certain ciphers could be not desired or did not work. This update gives administrators tighter control as it allows the administrator to specify an allowed list of SSL ciphers when the server is acting as a client for communication between two Certificate System subsystems. This cipher list is separate from the one stored on the server.
