sensuctl cluster-role create flags should be plural

[calebhailey]

Feature Suggestion

The sensuctl cluster-role create <name> flags should be --resources and --verbs (plural) instead of --resource and --verb (singular).

Possible Implementation

Sensu ClusterRole resources have roles containing resources and verbs fields (plural), but the corresponding sensuctl cluster-role create <name> flags are the singular form --resource and --verb, which is quite confusing. We might not want to deprecate the singular form flags to prevent breaking any existing user workflows – is it possible to alias them? Can both the singular and plural forms work?
