Sometimes, we will want to create a CMK for the cluster resources, can we add this optional functionality to the module?

@AsysGuptaSF, anywhere it is supported this feature should be available. Something similar to what we do here by overriding a default value with something the downstream defines.

we can use module arc-kms for this and override can be done @tsaucier-sf

Sure, still need the option available to the cluster and its resources. Default can be none, then the override variable to set a CMK as an input to the referenced module.
