Overview
UI provides day-1 operation to create cluster-admin during cluster creation

Acceptance Criteria
The list of requirements to be met to consider this Epic feature-complete

Customers can create a ROSA cluster with the CLI, UI, Terraform, and indicate the need for a cluster-admin user immediately after the cluster is installed without a day2-task being necessary. The customer could ideally send desired credentials to the cluster or receive them as a result of the request for the user, all at cluster-creation time.

• The ROSA provisioning UI can also have a toggle to setup an initial cluster-admin user
  • the username/password is provided to the user in the UI in a safe/secure manner
• credentials are not stored in our Red Hat systems unnecessarily or are cleaned up securely.
• the same facilities above are available to OSD clusters (in the OSD UI)
