Application name in this screenshot is "Theia SlapOS theia" because I requested with instance name "theia".

There was wrong configuration of alpn h3, which defined globally, but
overridden by slave specific configuration. Thanks to this fix, on a node
which is QUIC enabled, the QUIC possible slaves are working well.

Unfortunately real world deployment is using iptables, which is not consistent
regarding the port advertised to in case of UDP, thus it's required to force
the user to set the "virtual" listening port.

Required components are added, and in order to be really on the bleeding edge
for experimental and fresh features pick up recent curl version.

Allow to use --alt-svc for the http3 flavour, as it is quite imporant switch
for HTTP3 feature.

Based on https://curl.se/docs/http3.html

Add a webmanifest and a service worker for to support "Add to home screen"

When the backup script takes more than one second the file name is not
20500101000000.sql.gz

This brings support for 2020-12 schemas. The python2 version is
left unchanged

should fix crypt issues with python 3.9

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).

Without this commit, compilation fails with:

libiconv 1.14 doesn't compile on aarch64 with the following error:

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.
