Currently, the usage of standard lua library is always disabled, making it difficult to implement complex health check scripts.
This feat allow admins to control the usage of standard library by setting "health.lua.useOpenLibs" (merged-keys convention)/"resource.customizations.useOpenLibs.<group_kind>"
(split-keys convention) field in argocd-cm ConfigMap.
