Sleep method for JavaScript engine

A new Zabbix.sleep() method of Zabbix object has been implemented into JavaScript engine. It will allow to pause JavaScript execution if required. For example, it may be useful in webhooks when working with two separate services, which have a delay between data flows. The method accepts milliseconds as argument, e. g. to delay for 15 seconds:

Zabbix.sleep(15000);

A new template pfSense SNMP is now available for out-of-the-box monitoring.

You can get this template:

• prefer the IP from IP-subnet with default gateway
