This is a database-level field, not related to the application-level 'config_version', except as described in the following docs. If specified, checks for conflicts against 'x-cloud-resource-version' from the GET request (the GET's 'config_version' should be left blank if the IC is configuration controlled, ie to get the latest configuration)
only_test_versionboolean
If true, the testing version (version -1) will be permanently deleted but the latest IC version will remain untouched. Defaults to false
