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

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 )
