Validate service label and annotation absence

[allanrogerr]

When the users delete labels or annotations from serviceMetadata, the operator should delete the corresponding label or annotation from the service. This is to maintain the expected and actual service definitions in sync.

Currently, if an entry is deleted from the serviceMetadata element, the corresponding label or annotation remains on the corresponding service.

This fixes #2038
