How to use Splunk Terraform Provider to Delete a User?

[CDMcDaniel]

Looking at the Terraform provider documentation, I do not fully understand how a user is deleted using the "splunk_authentication_users" resource. 

Referenced here:  https://registry.terraform.io/providers/splunk/splunk/latest/docs/resources/authentication_users

I also looked through the provider source and examples and could not make heads or tales out of it: https://github.com/splunk/terraform-provider-splunk  as well as the REST API: https://docs.splunk.com/Documentation/Splunk/latest/RESTREF/RESTaccess#authentication.2Fusers

Any help is appreciated! 

Thanks,
Chris
