Checkmk Werk 12767: added tags and labels to cmcdump exported and imported data

ID: 12767 Title: added tags and labels to cmcdump exported and imported data Component: cmc Level: 1 Class: Bug fix Version: 2.3.0b1 It's now possible to use searching or filtering for tags and labels in hosts/services resulting from cmcdump ex- and import. Microcore configuration generation takes into account that tags and/or labels could be missing because export has been done with former versions.
