- List of configuration files that are used to generate the hash for the service wrapper's name.

/reviewed-on nexedi/slapos!333

The main idea is to rename the service wrapper using a hash of the corresponding configuration files. In that way, if the config files are updated, the corresponding script file, section in supervisor.conf and service process will be updated accordingly.
- the file name in wrapper_path contains a hash of the corresponding config files
- when config files change, and therefore the hash, the wrapper will be re-created and the corresponding service restarted
- the config files paths will be a parameter in the corresponding buildout section, if it isn't set there won't be hash-check

The exposed apache_custom_http option for custom slave was
incorrectly missing, and apache_custom_http*s* was used instead.

- destination server gets its own server id
- this removes complexity at the cost of respecting consistency in names
- http-send-name-header is not well supported by haproxy and that it may leads to random errors with not well formated request

Currently cloudooo does not compile with gcc 6.3 ( default gcc from current debian stable ) because of ffmpeg component:

Because we don't use ffmpeg in cloudooo, I'm just temporarily removing it .

To be compatible with buildout (and not only `slapos.recipe.template:jinja2`)

Running this buildout:

```
[buildout]
parts=x

[userinfo]
recipe = slapos.cookbook:userinfo

[x]
recipe = plone.recipe.command
command = echo "Hello user id ${userinfo:pw-uid}"
```


In a slapos patched buildout it outputs: `"Hello user id !py!991"` (which means it's not usable for references directly in other buildout parts)

In a "non patched" buildout fail with error:

```
While:
  Installing.
  Getting section x.
  Initializing section x.
  Getting option x:command.
  Getting section userinfo.

Proftpd with sftp and virtual users

http://www.proftpd.org/docs/

# Features

 * sftp only is enabled
 * partially uploadloaded are not visible thanks to [`HiddenStores`](http://proftpd.org/docs/directives/linked/config_ref_HiddenStores.html) ( in fact they are, but name starts with `.` )
 * 5 failed login attempts will cause the host to be temporary banned


# TODO

 * only password login is enabled. enabling [`SFTPAuthorizedUserKeys`](http://www.proftpd.org/docs/contrib/mod_sftp.html#SFTPAuthorizedUserKeys) seems to break password only login
 * log rotation
 * make sure SFTPLog is useful (seems very verbose and does not contain more than stdout)
 * make it easier to manage users ( using `mod_auth_web` against an ERP5 endpoint or accepting a list of user/password as instance parameter )
 * allow configuring webhooks when new file is uploaded

The build of nodejs uses python, and python leaking from the system can lead
to unexpected results, thus use provided from SlapOS.

To run tests from software/proftpd/test

To run tests locally by `python setup.py test`

This is a new kind of test suite that compile software, request instance
with specific parameters and check that the instance works as expected.

@alain, @rafael 

Test is here: https://nexedi.erp5.net/test_result_module/20180412-3688F368/2/view

Its failures which are different from  master one (https://nexedi.erp5.net/test_result_module/20180412-3501D1A/1) seems unrelated to my changes thus I propose to emrge it in and include in next webrunner release.

This reverts commit 1bdac5da.

This commit breaks webrunner resilience importer. This is not the proper fix

Because of this: https://lab.nexedi.com/nexedi/slapos.core/blob/master/slapos/grid/promise/generic.py#L44

When slapgrid run promises, it now save promise logs. Thus we need to logrotate them.
Thanks @Alain.
