Update Storefront to integrate with IBM Verify as CIAM

[sreenipamidala]

Background: Consumer identity and access management (CIAM) re-defines how companies interact with their customers and manages/secures their accounts. Within the Consumer and Travel market, we don't have any retail specific demo. However the CIAM demo is based on a TrustMeInsurance webpage. We would like to use IBM Garage Storefront since it has most ingredients and need to have IBM Verify integration to build the demo.

Also change the storefront catalog with Clothing store to make it even more compelling.

Activities: Integrate IBM Verify for the backend storefront
Integrate Frontend app w/IBM Verify
