[FEATURE] serveIndex: use serve-index for serving the application index

[jkoenig134]

My changes

• using https://www.npmjs.com/package/serve-index for serving index files
• Index is now more user-friendly
• implements possibility for @ui5/cli to show hidden files and choose a view (tiles or details)
  createMiddleware has now therefore 3 arguments (the new one are optional -> no beaking changes
  createMiddleware({resources, tiles, showHidden})
  • the resources object stays the same
  • the tiles object boolean declares if the ui should show tiles or a detailed table
  • the showHidden boolean declares if dot files should be hidden or not

Hey @jkoenig134, thank you for this PR! 🙌

Since serve-index is licensed under MIT, we need to include the license and properly attribute the code to the serve-index project.

We'll do both in a follow up PR since we might need to do some minor refactoring to better separate the original serve-index code from ours.

For future reference, a related PR: expressjs/serve-index#67

Hey @RandomByte, thank you very much for approval and merging!
I will add a PR at @ui5/cli soon, for integration of the tiles and hidden functionalities.

[RandomByte]

Cool, looking forward to it! Just to let you know, in #254 we swapped the API from tiles to showDetails (defaulting to true). We are thinking of reworking the HTML template somewhere in the future, maybe using UI5 Web Components 🤔. So better to keep it generic.

Are you thinking of exposing these options as CLI parameters?

[jkoenig134]

@RandomByte the options are beeing exposed in my new pull request for @ui5/server, upcoming in the next minutes. I TOTALLY forgot this in the last PR...

Released as part of UI5 CLI v1.12.0 🎉
