Going Go1.16.10 -> Go1.16.13 brings in fixes to compiler, runtime and stdlib
including security fixes to syscall and net/http packages.

https://go.dev/doc/devel/release#go1.16.minor

Tested manually via adjusted helloworld because nothing intree currently uses Go1.16.

Without this we sometimes hit the socket path length limit when testing
ERP5 inside Theia inside erp5testnode.

wait a first time that ERP5 have finished processing activities for
initial site creation and tolerate that during this time zopes might
reply with error code

With ERP5 commit erp5!1529
timerserver is started from wsgi startup script and the config in zope.conf
only applies to the medusa/ZServer mode.

Since ERP5 commit 8f3b77517e (Force use of the new TimerServer, 2019-09-13)
the timerserver egg is not longer used, so it's not needed to install
and configure it.

In ubuntu 21.04 (libc6 2.33-0ubuntu5) or current debian testing
(libc6 2.32-5) no longer use open to open /etc/hosts, but what appears
as "openat" in strace output - but can not be replaced by defining an
openat function.

This uses https://github.com/figiel/hosts which uses another approach
of replacing getaddrinfo, gethostbyname* and inet_aton.

Users have been updated a bit, because there are some small differences:
 - the /etc/hosts replacement file is defined by HOSTS_FILE environment
   variable, not HOSTS
 - the library name is libuserhosts.so, not userhosts.so

Other notable differences, for which we did not need code change are:
 - the new library also try to load a file when HOSTS_FILE is not set
 - the new library still use original /etc/hosts file
 - the new library supports aliases to hostnames, not only ip addresses

on debian 11, old software does not compile with an error like:

    ERROR: ld.so: object '/srv/slapgrid/slappart47/t/dcm/i/0/tmp/shared/userhosts/e880bfd75804e2ec50f297b173a4ae9a__compile__/userhosts-1d3b463e7856db6e674a06258c0840206e6a7b72-1d3b463e7856db6e674a06258c0840206e6a7b72/userhosts' from LD_PRELOAD cannot be preloaded (cannot dynamically load position-independent executable): ignored.

the fixes have been backported to a new 1.0.167.5 tag

This test is installing an old version of ERP5 that did not satisfy all
the software checks. We don't want to check the old version and we check
the new version in software/erp5/test so no need to check here.

instance-repman-slave-input-schema.json: Move parameters that are used for cluster to
`repman-cluster-dict`
cluster-config.toml: autorejoin and autoseed parameters are moved to cluster config file

multiarch() is being removed from slapos.recipe.build , it was not
needed because we can achieve this with buildout conditional sections as
we did here.

Test defining setUp and tearDown needs to call methods from super class,
where snapshots are collected.
