This section defines the Terracotta server instances present in your cluster. One or more entries can be defined, either directly under the <servers> element or in the
/tc:tc-config/servers/mirror-group. If this section is omitted, Terracotta configuration behaves as if there's a single server instance with default values.
This section also defines certain global settings that affect all servers, including the attribute secure. This is a global control for enabling ("true") or disabling ("false" DEFAULT) SSL-based security for the entire cluster.
