The ngx_http_realip_module module is used to change the client address and optional port to the one sent in the specified header fields.

so that the client IP is no longer the frontend IP, so rack

- removes wkhtmltopdf entry ;
  as cloudooo has a hack to use wkhtmltopdf
  (see 8b49da34 in cloudooo repository)

If there is no binlog in srv/backup/mariadb-incremental (ie : the parameter
incremental_backup_retention_days is set to -1), then the import script fails.
This should not happen as this script just updates some inline paths.
This commit just add a correct check on variables and files existence

Changing from dr-x------ to dr-xr-x---

It sometimes happend that buildout unistall/install the section with this recipe,
which remore storage_path file and recreate it. In most of cases this is not wanted
because the recipe is used to generate password, so that password will change when this
happend.
To prevent buildout to remove storage_path, I introduced a new option 'create-once'
which, when set to True (the default value) will not let buildout play with storage_path file
by returning None in install recipe. Also install won't remove the file if the size is not 0.

Each loop in jinja2 has its own scope. This code was likely relying on a
bug, which was probably recently fixed upstream.
Using generators is cleaner as it better expresses the intent.

Jupyter: Add extra_data_list option to support display data similar to the original jupyter python backend.

slapos.cookbook:generic.zope.zeo.client did not let buildout know about
site.zcml file it creates. So it would not be deleted on update, making
slapos.cookbook:symbolic.link fail as it carefully avoids deleting
non-links.
So, copy site.zcml instead of sym-linking.

Needed by ERP5 software release.

Such complex recipes prevent evolution. Split it into individual
components already covered by existing recipes.
