Using a reference to icinga variable in icinga2::object::notification $interval

[triforce]

There is a regex validation check on the $interval variable in the icinga2::object::notification resource type, however this could potentially contain just a string with reference to an icinga variable, such as "service.vars.notification.interval" causing the validation check to fail.

Current Behavior

validate_re() on $interval fails when checking against reference to icinga variable.

Possible Solution

• Extended the regex to something like (^\d+(\.\d+)?[dhms]?$|(service|host)\.vars.*)
  OR
• Add a $custom_cfg array parameter into the icinga2::object and all object types (notification, host, user etc) allowing a user (at their own risk) to add custom configuration.
  OR
• Replace the validate_re() with validate_string() on the $interval variable.

Your Environment

• Module version: 1.3.5
• Puppet version: 4.10.8
• Operating System and version: Debian 9
