KVM which defaults to 1024 RAM, 10 GB disk and 1 CPU is too small for nowadays
OS requirements, so to avoid confusions, increase the defaults.

Because of a bug in checkSoftware ( nexedi/slapos.core!339 ) we did not check some .so for missing rpath.

Add the missing rpaths now that these are correctly detected by checkSoftware

See merge request nexedi/slapos!1064

Sometimes on testnodes hugo refuses to start because:

    Error: add site dependencies: create deps: failed to create file caches from configuration: mkdir /tmp/hugo_cache/default: permission denied
    Total in 0 ms

new cmmi recipe prevent from having twice the same environment variable.
Also correctly setup swig libraries and fix gobject-introspection compilation.

Adapt all promise sections to changes in plugin promise recipe.

As Debian Bullseye has been released, set it as first option.

As Debian Buster 10.11 update has been released, upgrade it.

The real predicate to find the master partition is rejected slave publisher
configuration.

After upgrade to OpensSSH 8.8p1 the simple ssh-rsa keys are not accepted
anymore.

Also move component/stunnel to unstable

powerdns needs a pkgconfig file from lua to compile

nis module is linking against system libraries

This is almost the smae as for python3 (see e1cee1fc)

Without this fix, selecting a completion with the keyboard is not really
possible.

This reverts commit fb3ee44e
partially, for dream.

Add tests for Wendelin Learning Track tutorial

Add port-listening promises for all sources found in fluentd configuration file

There can be a short delay until the partially uploaded file is actually
removed, so wait a little bit before checking for its absence.

Our old subversion does not seem to support the expiration of letsencrypt root certificate, as we can see in [tests](
https://erp5js.nexedi.net/#/test_result_module/20210930-70CDB278/143): 

```
ClientError: ("Unable to connect to a repository at URL 'https://svn.erp5.org/repos/public/erp5/trunk/bt5/test_web'\nServer SSL certificate verification failed: certificate has expired", [("Unable to connect to a repository at URL 'https://svn.erp5.org/repos/public/erp5/trunk/bt5/test_web'", 230001), ('Server SSL certificate verification failed: certificate has expired', 230001)])
```

This is also what we observe when using svn command from ERP5 software release:

```

```

Updating subversion and linking it with openssl 1.1 seem to solve the issue.
