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

ソースファイルやテストは指定されていません。まず `ops cloud eks config` の背後にある既存のタスク言語コンフィギュレーターを見つけ、次に提案されているエントリーポイント `ops -configurator description.json` とディスクリプターフィールドを確認してください。完了条件には、一覧にあるフィールド型のインタラクティブな値、設定変数の保存、Kubernetes CRD としての設定の保存および読み込みが含まれる必要があります。
