The recommended approach is now to generate a font.conf file using
slapos.recipe.template:jinja2 since font.conf now needs entries for all
directories containing fonts.

Instead of the previous approach which relied on a side effect of
installing *-fonts parts that would write in parts/fonts/ and make the
fonts automatically available to applications, use a new approach where
each part is "pure", without side effects.
To make the fonts available to applications, a fontconfig font.conf
listing all the parts with fonts needs to be generated and set as
$FONTCONFIG environment variable.

A template font.conf is included in component/fontconfig

We now need to refer to the part where the dictionnary was installed.

this allow to share aspell component. Users needs to install the part
with dictionnaries, ie. aspell-en-dictionary instead of simply aspell

apr and apr-util are now build separately. I'm not sure there was any
benefit with that approach of copying the directories inside apache
source tree before build.

Using extra modules, like apache-antiloris require to install apache in
non-shared mode.

This also removes apache-antiloris from cloudooo and erp5 stacks so that
they can use apache as shared. Even if the section was installed, this
was not used anywhere.

log accesses (the logrotate conf already exists for them), and
remove the pattern "<IfDefine Port>" which was used when this
apache conf was extended by the software's apache extending
the monitor stack

Testnode expose the log folder for test suite, so that they can expose more logs and snapshots.

Because these can be big, we expose a new "keep-log-days" option so that we can se shorter delay for test nodes running software release tests.

Another important visible change is that testnode now automatically restart when configuration is changed.

Allow to configure the number of days to keep logs

Use NameWidth=* so that long filenames are never truncated

Use SuppressColumnSorting to disable the ablity to sort so that we can
wget -r all the logs for local analysis

sleep so long between retries

This recipe now uses strings for ip

if last_backup was an int, the script failed with this error:

result undefined, global datetime = <module 'datetime' from '/srv/slapgrid/
slappart6...6d33cee74/lib/python2.7/lib-dynload/datetime.so'>,
datetime.datetime = <type 'datetime.datetime'>,
datetime.datetime.fromtimestamp = <built-in method fromtimestamp of type
object>, last_backup = '1587724103'
<type 'exceptions.TypeError'>: a float is required
      args = ('a float is required',)
      message = 'a float is required'

This was broken in 8725ab1a.

fix the way of getting parameters in the new recipe.

 * fix section pbs in instance-pull-backup.cfg.in after change of
argument names.
 * fix the order of the 2 callbacks as the order is very important
