[Feature Request]: Use defaults to init the cache creation wizard

[dpanshug]

Feature description

In the Cache configuration wizard, we currently have static defaults coded into the form. To enhance flexibility and maintainability, we propose utilizing the REST API to dynamically retrieve defaults and populate the form fields accordingly. This will improve the wizard's user experience and ensure that it always reflects the latest defaults available.

To-Do :

1. Integrate REST API: Establish a connection to the REST API endpoint to fetch default values for cache configuration.

2. Populate Form Fields: Modify the wizard to populate form fields with the fetched defaults, ensuring that these defaults are displayed as initial values for the variables within the modal.
