- make cloudooo services use same name as in haproxy, this was off by one (service cloudooo-0 was cloudooo_0 in haproxy)
 - test cluster functionality (to catch bug from nexedi/cloudooo!29 )
 - update cloudooo with that fix
 - make sure we set an existant locale ( by using `C.UTF-8` ) and exercice a bit conversions involving characters encoding

See merge request nexedi/slapos!975

The "30" was not removed by mistake, which lead to activity timeout being 30,
instead of configured one.

See merge request nexedi/slapos!977

see nexedi/cloudooo@0b5ff71a

So that the service names match the backend names in haproxy

Libreoffice needs to run with an UTF-8 locale, otherwise it does not use proper
encoding for text files.
cloudooo sets a default locale as a fallback, but using en_US.UTF-8, which is
not always present (it is not present on capri testnodes). Anyway, this kind
of configuration is the job of slapos, so we prefer to have it done at slapos
level.

- pins component/fluentd gems version to fix :

  ERROR:  Error installing fluentd:
	msgpack requires Ruby version >= 2.4.

  encountered while supplying software/fluentd in a SlapOS Webrunner.

- removes outdated gem arguments '--no-ri --no-rdoc'
  by default `rubygemsrecipe` uses '--no-document' (see https://lab.nexedi.com/nexedi/rubygemsrecipe/blob/master/rubygems.py#L206)

- splits `gem-options` arguments to fit the README example (see https://lab.nexedi.com/nexedi/rubygemsrecipe/blob/master/README.rst#L50)

- adds minimal test to check fluentd SR instanciation

The keyboard option is actually not recommended in the QEMU
documentation
(https://manpages.debian.org/buster/qemu-system-x86/qemu-system-x86_64.1.en.html).
After some tests, it appears that noVNC is already sending raw keyCode
to QEMU since 2016 (see
https://github.com/novnc/noVNC/commit/f4f4e8993d6daeb43b957766cd6973993232ba13).

More information can be found in

rotate_size 0 or rotate_size -1 does not help to disable rotation, so
workaround it by setting very big rotation limit.

See merge request nexedi/slapos!968

It was formatted with a '\t', which json-schemas test does not allow.

We are not using this

This host header is not passed by default, because we are already using
proxy_set_header, so we need to set it explicitly.

It seems that since we updated some packages in in 279486fe (stack/slapos:
version up some eggs with known vulnerabilties, 2021-01-28) slaprunner was
producing URLs with "localhost" as hostname when using redirect(url_for(...))

As discussed in https://github.com/nextcloud/news/issues/1306 a new release was
uploaded.

Commit 2f4d8cf8 fixed the following error:

  Generating phar.php
  .../parts/apache-php__compile__/php-7.3.6/sapi/cli/php: error while loading shared libraries: libzstd.so.1: cannot open shared object file: No such file or directory
  Makefile:420: recipe for target 'ext/phar/phar.php' failed

and only -rpath is needed.

apache-php does not actually depend on zstd (hence the removal of the 'extends'
line) but there's something not smart:

Even though there is no integrated way of putting for fonts there, cloudooo supports additional fonts in `~/srv/font`

This was not working because of a leading space in the fontconfig
