implement (in golang) a configurator tool [alessandro sanino]

## Why you need it?

THere are many interactive configurators in ops: for example `ops cloud eks config`
They are implemented in task language but it is not ideal.
It would be better to provide a tool for it

## How it could be?
a tool in go doing ops -configurator description.json

where the descriptor can be like:

```
[{
"name": "WHI",
"label": "Why do you recommend Apache OpenServerless?",
"type": "textarea",
"required": "true"
}, {
"name": "JOB",
"label": "What is your job role?",
"type": "text",
"required": "true"
}, {
"name": "TONE",
"label": "What tone should the post have?",
"type": "text",
"required": "true"
}]
```

executing the configurator it will ask for the values and store then as configuration variables.

# Form Field: a dictionary
- `label`: the description
- `name`: the field used in the input
- `required`: is it required?
- `type`: can be `text`, `textarea`, `checkbox`, `radio`, `file`
- if `radio`:
- `options`: array of options
- if `file`:
- upload a (small!) file in base64

# CRD support

it is important that the configurator will be able to save the configuration as a CRD so you can put it in a kubernetes cluster and able to read them back as environment variables from a crd

Aucun fichier source ni test n’est nommé. Commencez par localiser les configurateurs de langage de tâches existants derrière `ops cloud eks config`, puis examinez le point d’entrée proposé `ops -configurator description.json` et les champs du descripteur. La réalisation devrait couvrir les valeurs interactives pour les types de champs indiqués, le stockage des variables de configuration, ainsi que l’enregistrement et la lecture de la configuration en tant que CRD Kubernetes.
