In a recent PR to ovn-operator, we introduced a function called deleteExternalConfigMaps[1] that is responsible for cleaning up configMaps created by configmap.EnsureConfigMaps from lib-common.

It would make sense to move the deleteExternalConfigMaps function to lib-common in the same module with EnsureConfigMaps and then reuse it from OVN operator (and other operators that are interested in cleaning obsolete ConfigMaps previously created.)
