- activate cu_config_link parameter
- update cu-config.xml
- add supervision log and nc session log

we should definitely get rid of this old golang version by upgrading gitlab

This is needed for Debian 12

This is needed on Debian12 so that binutils can recognize the system libraries. Without this upgrade we have the following error when trying to build gcc8.5 on Debian12:

/opt/slapgrid/shared/binutils/ea3cf4e44b2944e805d9fe6387a4eeb0/bin/ld: /lib/x86_64-linux-gnu/libc.so.6: unknown type [0x13] section `.relr.dyn'

This "simple" approach of using LD_PRELOAD to inject errors when using
inotify no longer works on glibc 2.34 and it's now much more complicated,
as we can see in discussions from https://stackoverflow.com/questions/15599026/how-can-i-intercept-dlsym-calls-using-ld-preload
or code from https://gitlab.com/torkel104/libstrangle/-/commit/720f0ba2ce4423ce5f3e7ebe135e126007365bac

This test was for reproduction of a very specific problem that does not
happen so much on modern linux which has a much higher limit of inotify
watches, the easiest is to remove this test now.

Promise from a8271791 (stack/erp5: new promise to check software
release URL of zope instances, 2020-12-04) was never executed. Adding
the section seemed to be change timing to make the upgrade test, but
this was not correct to not run the promise.

This reverts commit 9497c734.
This reverts commit c55337f2.

This causes other build failures on some environments.
Turns out, this was not even enough to get gcc to fully build on my
environment, so more fixes are needed.

Most tests were unaffected by partitions now having different IPv6.
The main issue is that there is now a .slapos-resource file in each
subpartition as well, same as in normal top-level partitions, which
interferes with a hidden behavior of slapconfiguration recipe that
allowed a kvm in a subpartition to transparently use the tap of the
top-level partition. Now we need to explictly take this tap and put
it in the .slapos-resource file of the subpartition.

Since slapos.core!515 services of stopped instance do not appear in
supervisord anymore.
