Describe the rationale for the suggested feature.
Right now there is no way to check unique values on nodes. Specifically in context of topology.kubernetes.io/zone labels this is a pain. E.g. for a set of nodes I am interested in determining if they span at least 3 availability zones (for HA purposes). That is a check that is hard to express currently.
Describe the feature
It is a straightforward change adding a new function to the node analyzers.
See: #2079
Describe alternatives you've considered
Alternatives include e.g. JSON analyzers, but this is a pay. The above allows for succinct expression of e.g. topology constraints.
