    Do not call Zabbix in case of deletion of cluster

    No reason to call Zabbix to report about changes because
    we delete node with it few seconds after.

    Also fixed:

    zabbix error respond may not contain data field

    Example:

    { 'jsonrpc': '2.0', 'id': '1', 'error': {
      'message': "Error connecting to database [Can't connect
                  to local MySQL server through socket
                  '/var/run/mysqld/mysqld.sock' (2)]",
      'code': 1}}
