[2.2.0] Checkmk Werk 16874 created: host_config: skip host parent validation on host return

Title: host_config: skip host parent validation on host return Class: fix Compatible: compat Component: rest-api Date: 1715689497 Edition: cre Level: 1 Version: 2.2.0p27 Prior to this werk, the REST API always validated if a specified host parent is an existing host. This validation behavior differs to the mechanism of the UI where it is possible that a host has non existing hosts as parent. This werk modifies the behaviour of the REST API to skip the host existence validation when a host is returned.
