This recipe will be used to generate promise in etc/plugin dir. It solve the problem of promise eggs
dependencies and allow to set custom parameter to use in promise.

The generated script will looks like:

    import sys
    sys.path[0:0] = [
      ...
    ]

    extra_config_dict = {
      'KEY': 'VALUE'
    }

    CONTENT

CONTENT is a python code, the expected content looks like:

    from namespace.module import RunPromise

then the promise section in buildout will be something like:

    [my-promise]
    recipe = slapos.cookbook:promise.plugin
    eggs =
      NAME
      ...
    output = OUTPUT
    content =
      from namespace.module import RunPromise

    config-KEY = VALUE

we now use slapos.cookbook:wrapper instead

kumofs is even abandonned software.

inotifyx does not support Python 3.

Since nexedi/erp5@6c6b77a0, this is now a safe
operation, in that a mistake while moving databases won't result in a loss of
the catalog if the zodb is empty.

This new implementation relies on
nexedi/erp5@6bb4c56e, which means that zopes
decide on their own to create the site at startup if there's none, and the
'erp5-bootstrap' service is removed from the root partition.

*  Includes a new recipe to get a random time
*  Moves generatepassword and generatemac into random.py
*  Fixes up some recipe, as the creation of a "random.py" file may collide
   with the import of the standard library random
