Helm values - convert JSON schema to a standard format

[sohel-rp]

Summary

Add functionality to convert JSON schema (values.schema.json) to a supported format which will be used by the GUI configuration view to render a form.

Motivation

Simplify fetching & conversion of values.schema.json to a standard supported format to be used for rendering the GUI form-based configuration view.

Proposal

1. Define a standard format to be used by UI (GUI view) to render a form
2. Fetch the values.schema.json
3. Parse it and retrieve the different properties with states like hidden, required, etc.
4. Convert retrieved data to a standard supported format.
