In Werk #13729 support for labels in CSV exports was removed (among other things). Instead, for affected columns a constant "NOT_CSV_EXPORTABLE" value was exported.

This change reintroduces host & service labels as JSON serialized strings. This only relates to CSV exports, other formats are not affected.

Sample export:

"host";"host_labels"
"test";"{""cmk\/os_platform"": ""linux"", ""cmk\/os_family"": ""linux"", ""cmk\/check_mk_server"": ""yes"", ""cmk\/site"": ""test""}"
"dummy";"{""my_label"": ""works""}"
"nothing";"{}"
