This reverts commit 8251f3dd.

1.4.23 is not available on pypi yet, causing all involved software releases
to fail instanciating, breaking all tests.
Feel free to reapply once the version is actually released.

Thanks to this 'None' is used in BuildoutSerializer

They are dependencies of slapos.toolbox and we already agreed to put slapos.toolbox version in a shared file.

   The version 1.0.84 was used by an existing tag on the
   version control, so it would be inconsistent to use this
   version number.

It will be used on python2.7

from https://docs.python.org/2/library/subprocess.html :
POSIX users (Linux, BSD, etc.) are strongly encouraged to install and
use the much more recent subprocess32 module instead of the version
included with python 2.7. It is a drop in replacement with better
behavior in many situations.

This is needed by slapos.recipe.cmmi

To fix the build of golang1.10, since the buildout process keeps
/dev/random and /dev/urandom open (where ?).

  The version 1.4.12 was broken so it required a re-release

( not needed for the current work on jsonschema draft 7 support, but
done at the same time, to merge together two unrelated changes which
cause recompilation so that we recompile only once )

jsonschema = 3.0.0a3 needs a recent setuptools, probably because it uses
setuptools_scm

jsonschema needs six>=1.11.0

Version and requirements information containing six:
  [versions] constraint on six: 1.10.0
  Requirement of mock==2.0.0: six>=1.9
  Requirement of slapos.core==1.4.11: six
  Requirement of bcrypt==3.1.4: six>=1.4.1
  Requirement of cryptography==2.3.1: six>=1.4.1
  Requirement of jsonschema: six>=1.11.0
  Requirement of manuel: six
  Requirement of cliff: six>=1.9.0
  Requirement of pyOpenSSL>=18.0.0: six>=1.5.2

with support for draft7 of json schema

So that we can use
nexedi/slapos.core!51
