Checkmk already supports reading and matching host and service labels
whose value contains : (see werk #18706). However, creating such
labels through the Setup UI or the REST API was rejected with the error
message "Labels need to be in the format [KEY]:[VALUE]".
With this werk it is now possible to enter multi-colon label values
from the Setup UI ("Host labels" / "Service labels") and from the REST
API host and folder endpoints. A value like net:ip:v4 is stored
verbatim and can be matched in rules as usual.
The label key still may not contain : because that character is used
as the separator between key and value.
