+minor cleanups user section was not used

Upload files feature uses a websocket at /file-upload , so configure frontends
to allow web sockets on this path.

When using nested slapos $HOME might not be set (which might be a bug in slapos
format) so set $HOME ourselves so that we don't use home files from the outer
slapos.

See https://github.com/eclipse-theia/theia/blob/v1.5.0/CHANGELOG.md#v150---27082020

Use newer nodejs as per requirement

Use vscode extensions for json and plantuml

This is current LTS

so that theia can use a local installation of rust using rustup

Introduce an easy way to run slapos commands in a more integrated way.

Instead of installing the software inside slaprunner from 1.0 branch, use the
same branch as the tested one, this should allow to see regressions earlier
(before they got merged in 1.0)

this profile was modified in c6cc45ab (all: apply eclint to unify empty lines
at end of file, 2020-08-05) but does not use buildout.hash.cfg, so md5sum was
not automatically updated.

Since f3613b91 (version up slapos.toolbox 0.110, 2020-08-21) slapos.toolbox needs lzma, which should always be installed with slapos component, because letting buildout install the egg from pypi would build against system libzma library (or fail if not present).
This introduce `*-dependencies` sections for eggs that have some dependencies that needs to be installed by slapos and use it, especially in section which install eggs from git for testing.
