[DISCUSS] Upgrade to Vue3 library

[Mai Nguyen <ho...@ext.ewerk.com>]

Hi All,

We are upgrading a Vue 2 application to Vue 3 on CloudStack. As far as our investigation goes, Vue 3 does support migration from Vue 2 to Vue 3 by using `@vue/compat` (aka "the migration build"). However, it is worth mentioning that there are some incompatible features (please refer to: https://v3.vuejs.org/guide/migration/migration-build.html#overview).
The biggest differences between Vue 2 and Vue 3 on Cloudstack are:
- mount: https://v3.vuejs.org/guide/migration/mount-changes.html#overview
- Slots: https://v3.vuejs.org/guide/component-slots.html#slots
- Async components: https://v3.vuejs.org/guide/migration/async-components.html#async-components
- Events: https://v3.vuejs.org/guide/migration/events-api.html#overview
- Watch: https://v3.vuejs.org/guide/migration/watch.html#overview

In order to make them compatible with Vue 3, it is necessary to upgrade or replace some libraries as well as some other components, which are listed below:
- Antd: https://2x.antdv.com/components/overview
- Router: https://next.router.vuejs.org/installation.html
- I18n: https://vue-i18n.intlify.dev/introduction.html
- Clipboard: https://www.npmjs.com/package/vue3-clipboard
- Vue-ls (https://www.npmjs.com/package/vue-ls) => vue-web-storage (https://github.com/ankurk91/vue-web-storage)

These upgrades and replacements will require changes in source code, structure and elements in UI. We would like to have your opinions about it.

Thank you and best regards,
