Rendering of Icinga2 global functions

[jonbulica99]

Expected Behavior

Consider the following rendered configuration:

apply Notification "update_checks_notification" to Service {
    import "mail-notification-service"
    period = "update_checks_period"
    assign where "Update Checks" in service.groups
    vars.customer_email = "{{ get_email_for_zone(service.host_name) }}"
}

I'm basically trying to get the function get_email_for_zone() to be evaluated. For our purposes, assume the function is defined as follows:

globals.get_email_for_zone = function(zone_name) {
    return "user@" + zone_name;
}

Current Behavior

The customer_email variable keeps getting interpreted as a literal string, probably because of the quotation marks the director puts around it.

Possible Solution

Much like the macros functionality, the director should check for the presence of opening {{ and closing }} before deciding whether to use quotation marks or not.

Steps to Reproduce (for bugs)

Define a Notification apply rule for services (probably not limited to Notifications) and try to set a custom property as follows: You should get a similar rendered config to the one shown above (Expected Behavior).

Your Environment

• Director version (System - About): 1.6.0
• Icinga Web 2 version and modules (System - About): 2.6.2
• Icinga 2 version (icinga2 --version): r2.10.3-1
• Operating System and version: Debian 9
• Webserver, PHP versions: nginx, php7.0

We also got this with service template - director interpets this like just a string.
