[2.3.0] Checkmk Werk 16138 created: host_config: set start field as nullable

Title: host_config: set start field as nullable Class: fix Compatible: compat Component: rest-api Date: 1695887849 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 This werk addresses a small issue with our host_config response schema. We in some cases return a null value for the start field in network_scan_result. This violates the response schema. To fix this, we set the schema field to allow_none.
