[FEATURE REQUEST] implement control of user input based on values.schema.json

I think we should control input from the user (enforcement by default, and let admin to do no control)

In user mode there is no need to implement some control because api only use user privilege.
But some implementation can disable user access to kubernetes and in this case we should carefully handle user input.

Some controle are directly done by helm without any effort but only values in values.schema.json are controlled by helm.
