Use the operator as an ops task task [alberto martino]

Experoment with refactoring the operator as an ops plugin.

Desidered effect:

git clone https://github.com/apache/openserverless-operator olaris-opsv

and you have the opsv plugin

```
$ ops opsv
* setup: manage installations

$ops opsv setup
* redis

$ops opsv setup redis
* create
* delete
```

then you can do use the commands to create and delete the plugin using the redis modules under nuvolaris

该 issue 没有指定文件、测试或命令入口点；首先定位 operator 和现有的 ops 命令实现。将当前结构与所要求的 opsv 设置以及 Redis create/delete 命令层级进行比较，并将完成标准视为一个能够公开这些命令且正常工作的克隆插件。
