By inspecting current configuration stored in .data-disk-amount of the
partition configuration directory extend the conflict protection to really
observed configurations.

Adapt the README to follow real messages and explain a bit more the situation.

Patch nexedi/slapos@15e26abd explicitly declared
go version 1.17 for the 'helloworld' SR.

This was done at a time when we already had [golang1.17] in component/golang,
but the default was still go1.16. The explicit declaration allowed the 'helloworld' SR
to already switch to the newest go version.

Since patch nexedi/slapos@d32524c3
we use go1.18 as our default version. In order to allow 'helloworld' to use our newest
SlapOS supported go version, it's therefore sufficient nowadays to simply remove the
explicit declaration.

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
