Checkmk Werk 12738: Skip empty values on bulk host import via CSV file

ID: 12738 Title: Skip empty values on bulk host import via CSV file Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 If values were missing for some hosts and this kind of value was selected in preview, e.g. "IPv4 address", importing was not possible because of a validation error. Such values are now skipped. The affected hosts are now imported without the missing value.
