What does this PR do?
Improves the parsing of "group resource" strings when using
kubernetes_resources_annotations_as_tags/kubernetes_resources_labels_as_tagsto support groups that contain periods. The updated code uses Kubernetes' own validations to ensure that the resource and group are RFC1123-compliant Labels and Subdomains, respectively.Fixes #33646
Motivation
The current validation logic requires that the key will contain only one period, meaning it's not currently possible to specify resources whose groups contain periods as is common with CRDs.
