User journey based CLI input

[albertwo1978]

Create a CLI input (ie. --cuj) to specify a customer user journey and use that input to trigger a specific deployment type on top of the base build ex:

--cuj gwapi-single-region : Deploys multiple clusters with Gateway API for ingress in a single region
--cuj gwapi-multi-region-acm. : Deploys multiple clusters with Gateway API for ingress in a single region and ACM
--cuj workload-identity : Deploy a workload identity demo application

CUJs could exist in a sub-repo /customer-user-journeys and we can document a template / process for adding to this repo and extending the number of CUJs through community support.

CUJs under the hood leverage the base CLI to deploy the proper base environment and extended resources.
