test.cfg becomes the python3 version
a new test-py2.cfg is introduced
test-py3.cfg is removed

cf slapos commit cc7f36a0 (component/defaults: use python3 by default, 2022-08-27)

Change python2 softwares to use python2 explicitly and python3
softwares to use the default, but leave a few softwares (html5as,
html5as-base, fluent-bit, packer, seleniumrunner) using the default
python, as they were using python2 not because they only support python2
but because they don't have strong dependency to the python version
being used.

Resolve `@theia/core` subdependency `vscode-uri` to a locally installed patched version, to workaround https://github.com/microsoft/vscode/issues/154048.

This fixes access to Theia through the IPv6 `backend-url`. That issue was discussed in nexedi/slapos!1204

The patched version of `vscode-uri` is published here: https://github.com/xavth/vscode-uri/tree/fix/ipv6_url_authority

To do this, `yarn.lock` was regenerated, so this also caused a version up to Theia 1.28.0.

Instead of lying in tests and checking for NotReadyYet in the connection
parameteres use promise to assert that generation of KeDiFa URLs is really
ready.

Drop hacks applied in the test, so that it will uncover all missing promises
and corner cases.

bootstrap-script-url and data-to-vm are important features of
enable-http-server and are expected to work correctly, thus cover them
with instance-level testing.

In mean time fix detected issues.

We disable sql_log_bin while managing repman_slave_definition database and
destroying slave database. Else, changes are replicated which can break
slave node.

edgebot is dropped too, as it was shared instance implementation for edgetest.
