Support Sharing Services in Operations

New commands added in cf cli 6.35.0:

   share-service - Share a service instance with another space

USAGE:
   cf share-service SERVICE_INSTANCE -s OTHER_SPACE [-o OTHER_ORG]

OPTIONS:
   -o      Org of the other space (Default: targeted org)
   -s      Space to share the service instance into```

And

```NAME:
   unshare-service - Unshare a shared service instance from a space

USAGE:
   cf unshare-service SERVICE_INSTANCE -s OTHER_SPACE [-o OTHER_ORG] [-f]

OPTIONS:
   -o      Org of the other space (Default: targeted org)
   -s      Space to unshare the service instance from

首先定位客户端现有的服务实例操作，并将其命令映射与此处所示的 share-service 和 unshare-service 用法进行比较。验证服务实例、空间、组织以及 force 处理所支持的参数；完成的标准是两个操作都以一致的方式提供，并由项目现有的检查覆盖。
