当 higress 用 helm 安装后，执行hgctl upgrade --from-helm 表示从用helm安装higress时设置参数生成 hgctl install profile。可以通过 helm status RELEASENAME -oyaml 命令读取 helm 安装配置参数。 |

@sjcsjc123 如上面Jun所说，这个issue的目的是继承helm安装时的参数，从而完全替代helm安装方式 |

helm upgrade的时候要将profileName设置为k8s还是local-k8s，目前的思路是如果指定了from-helm参数，通过helm status获取config的值，将其转化为valuesOverlay，通过 |

是否是 local-k8s 是根据 global.local是否 True来判断, 同时 profile里的global 设置是否可以从 helm 安装安装参数中恢复？ |
可以恢复出来 |

升级时候 如果 --from-helm = true， 可以读取helm 安装所有 release 列表，让用户选择升级那个 release, 如果用户选择某个RELEASE 后，要检查这个 RELEASE 是否已经升级（ 是否已经有 install profile),如果没有让用户升级。

Ⅴ. Special notes for reviews
简单debug了一下，运行hgctl upgrade --from-helm命令后进入如下地方，已经可以看到更换到latest版本号
upgrade本质上也是install命令
