### Description

It's not obvious to people that we provide integrations with testing and linting solutions even though they exist. Folks have to run `ng e2e` to see the supported testing frameworks and after that run `ng add [solution]`. Alternatively, for linting they have to run `ng lint` to get ESLint installed, but none of the tools comes by default.

### Describe the solution you'd like

To better inform developers about the integrations we provide, we can update our setup experience. When folks create a new project we can show two prompts:

```
- Which end-to-end testing framework you want to use:
- Cypress
- Nightwatch
- WebDriver
- None
- Do you want ESLint? (Y/n)
```

If folks select `None` and `n` they should still be able to add e2e/linting to their projects with `ng add [schematics]`. If people select an integration we can automatically run `ng add [...]` at setup time for them.

從 `ng new` 設定流程開始，追蹤 `ng add`、`ng e2e` 和 `ng lint` 目前如何提供整合。定義提示及其選項，然後驗證選取某個整合會呼叫預期的設定，而選取 `None` 或 `n` 時，專案仍可繼續使用後續的 `ng add` 命令。
