Set in preferences the path of this interpreter, for example:

```json
{
  "python.pythonPath": "/srv/slapgrid/slappart19/srv/runner/software/91be79296dea036ad98d4aff08ecb74b/bin/python"
}
```

then when editing products files completions and jump to definition should work. It works but it is sometimes so slow that it seems not working.

This macro generates an intepreters knowing its own sys.executable, so
it can be used as interpreter for theia's python extension to provide
code navigation, completion etc.

  This feature isn't used anymore. We support a two schema per software
type (at most):

    One for Software Instance
    One for Shared instance

Since theia 1.23.0 ( https://github.com/eclipse-theia/theia/pull/9820 ),
/file-upload is a simple HTTP endoint and no longer needs to be websocket.

Since 1.23.0 ( https://github.com/eclipse-theia/theia/pull/10514 ),
Theia uses socket.io and it needs /socket.io to support websocket,
otherwise it falls back to HTTP polling, which is significantly slower.

This version of scons only support python2

no need to prompt everytime. In the context of slapos theia, I guess we
can say that user trust the workspace

This is longer needed since years, also the part looks broken.

Reintroduce a patch to fix build error:

    execvp: printf: Argument list too long

that seems to happen again with nodejs 16.

Also add a note for minimal supported version, that will have to be
set in software

This partially reverts ee733f9d because
of issues with python3

Commit ee733f9d (version up: zc.buildout 2.7.1+slapos017,
slapos.libnetworkcache 0.23, 2022-03-28) introduced a new way of
computing cache key used for shacache and downlaod URLs that were only
in cache but no longer available from their original location no longer
could be retrieved. This update the original download URLs to URLs that
are valid today.
