[request] no-unsupported-features supports Node.js APIs other than ES features

[teppeis]

Currently no-unsupported-features only supports ES features.
Moreover, I think that it's wonderful if the Node API is also supported.

For example

• new globals: URL, URLSearchParams (since v10.0)
• new modules: require('http2') (since v8.4)
• new module path: require('fs/promises') (since v10.0)
• new module methods: fs.copyFile, fs.copyFileSync (since v8.5)
• new module props: require('assert').strict (since v10.0)

I guess it's difficult to detect methods or props, but not impossible only for main case.

Thank you for this issue.

Yes, this plugin should detect those. I have a plan to separate no-unsupported-features rule to no-unsupported-ecma-features and no-unsupported-node-features rules.

Great!
