Depending on the scope, metrics can have different names. For instance, the number of active/backend servers are reported with "haproxy_backend_active_servers"/"haproxy_backend_backup_servers" metric names in the backend scope while it should be "haproxy_server_active"/"haproxy_server_backup" in the server scope. To be able to support different names depending on the scope for the same metric, arrays of ISTs were added, one by scope (front, back, listen, server). These arrays only contain names overriding the default ones. Note: the exemple above is not supported for now and is the reason for this commit.
