Add NodeJS server as an alternative to PHP

[limaanto]

Problem

I wanted to have an app similar to my_webapp but with nodejs instead of PHP.
After hesitating to create a new app, I decided it was better to improve this one instead.

Solution

For this, I added, with the help of @oiseauroch:

• Two entries in the manifest:
  • A choice for the NodeJS version
  • A port (provisionned in any case due to ynh limitations, but this should not matter)
• Services and configs:
  • Systemctl configs to run the NodeJS server
  • A watcher service and path to restart NodeJS upon file update
  • A custom NGinx config because it is incompatible with the default one
• Docs:
  • More info in the description and admin

The install/remove/backup/restore have been adapted and tested.
The upgrade script is updated but not tested
The change_url script does not change

It is not possible to have both PHP and NodeJS to keep the scripts simple.

This sounds cool but i don't know what to think about this ... This raises the question of what really is the scope of this app. Somebody could also add support for Python, Ruby or whatever and we end up in Feature creep hell

To me the support for PHP+SQL db should already justify splitting the half in two apps, once for pure static hosting (possibly with Git actions in the config panel) and the other one for PHP(+SQL). There's also the Flask app, which is somewhat similar but for Python ... Imho we should really discuss wether we want a single my_webapp that fits every use case, or several "my__webapp" that are skeletons that are design for specific technologies

Hi! Thanks for answering so quickly
I agree that this is not as clean as I first though. Just with nodejs, I saw a lot of edge cases that were hard to keep track of, and this will only get worse.
Maybe it was a mistake to directly open a PR and we should first discuss this in a dedicated issue. In this case, I'll be happy to participate in the discussion :)
