Missing import modifier to check for existing director host

[slalomsk8er]

Expected Behavior

It is easy to create a import source, that creates services and the sync will not fail because there wasn't a host object to attach the service to.

Current Behavior

Sync rule will fail on the first row where the host object can't be found in the director.

Possible Solution

Add a modifier to drop rows with invalid/unknown hosts.

Steps to Reproduce (for bugs)

Create a import and sync rule with the x509 module as source and try to attach a services named "x509 - HOST/IP:PORT" to HOST.

Your Environment

• Director version (System - About): 1.10.3.2024020901
• Icinga Web 2 version and modules (System - About): 2.12.1
