This should only be used for development

and clean up some duplicate version pins

We have two public cloudooo instances, https:///cloudooo.erp5.net/ and
https://cloudooo1.erp5.net/ but the software release uses only the first
one. This changes to use both instances by default, in a random order.
This happens for the ERP5 instance and also for the test runner.

This also includes a breaking change: the parameter is renamed from
`cloudooo-url` into `cloudooo-url-list` and instead of being a coma
delimited list of URLs, this is now a proper list of URLs.

Some obsolete code and comments about the old `erp5-cloudooo` partition
that used to part of ERP5 software release have also been removed.

On testing side, ZopeSkinsMixin._setUpClass is changed be made more
robust, by waiting that all activities are processed and using a new
xmlrpc client in every iteration ( to prevent issues like the one from
https://erp5js.nexedi.net/#/test_result_module/20230107-548523A7/10 )

Following up on 6506625f (software/jupyter: Move pinned eggs to
slapos.cfg, 2023-01-06), we need to keep a traitlets pin that is
compatible with python2, for component/pygolang/test-py2.cfg

This is getting rid of obsolete Caddy 1 software.

This is also making the public/ directory really public (no need for authentication).

Before this patch all ERP5 SlapOS Integration tests only run with ZEO
storage. We should also run them against NEO, because we are using
ERP5 with NEO in SlapOS.

In order to do so we implemented parameterized test classes for our ERP5
integration tests. Each test case can be configured via its __test_matrix__
attribute. A test matrix is a dict which maps the flavoured class name suffix to
a tuple of parameters. A parameter is a function which receives the
instance_parameter_dict and modifies it in place. You can use the
'matrix' helper function to construct a test matrix. If .__test_matrix__
is 'None' the test case is ignored.

In the same time extract described variables to be available in the comment
context.

Changes:

 * clean up tests from simply removing headers before asserting
 * check out unstable headers and correct them
 * improve assertion name

Adapt tests to cleaner responses from Haproxy.

It's just type:websocket without any path and with transparent parameter,
thus resulting with providing X-Real-Ip to the backend.

haproxy supports websocket by default everywhere, so reuse this and make
type=websocket only needed if some specific configuration like
websocket-path-list or websocket-transparent have to be set.

As a result of implementing this feature X-Forwarded-Proto and
X-Forwarded-Port header support is now enabled per slave and not just
globally.

X-Real-Ip is only available for websocket paths, previous implementation
was simply wrong, and this has been fixed and asserted in tests.

Tests have been slightly updated to make it easier to follow the real
websocket logic.
