This is a workaround to avoid the UnicodeDecodeError that occurs
when installing wheel, in particular during compilation of ERP5.

Provides dnsresolver tool.

Install setuptools_scm before python-dateutil (which has it in setup_requires) so that the version can be controlled by buildout

See nexedi/slapos@f1e7230e

Factor-out things that provide components for ZODB stack from software/neoppod/
into component/ZODB/.

The version >=5 is not python2 compatible.

Introduces devperm manager with lsblk.

Changes:
- Add comments and reorganise instance.cfg.in for clarity
- Select free ports instead of hardcoded ports
- Upgrade to slapos.core 1.6.5 to prefix forwarded requests

This makes it possible to recursively nest theias into theias.

See merge request nexedi/slapos!919

pyrsistent has a setup_require of pytest-runner. Buildout installs
setup_require from their latest version, regardless of [versions]. When a
new version of pytest-runner was released without python 2 support this
broke installation of software releases on python 2.

This reverts commit c2a7ed05.

`autorun` controls the `slapos-node-auto` service:
  - `running`: start `slapos-node-auto`
  - `stopped`: stop `slapos-node-auto`
  - ( else ) : leave `slapos-node-auto` as it is

This reverts commit b3394953.

also update slapos.toolbox to 0.116

Since Jinja 2.11 it's possible to do nice tests against true, false and
others, which is important for various type checks.

moves python2 release to component/jupyter-py2 because it is required by ERP5
but not maintained anymore

moves to python 3 :
- test/test.py
- jupyter_notebook_config.py.jinja
- ERP5kernel.py

modifies custom.js to create a workaround for events issue
see (https://github.com/jupyter/notebook/issues/2499)

upgrades slapos.cookbook version to 1.0.171 to use zero_knowledge recipe
with python 3

adds jupyter partition check in software/erp5/test/test_erp5.py

Jérome reports that Pygolang build on Python3 fails because geventmp turned out to be not pinned:

nexedi/slapos!862 (comment 121359)

Geventmp is indeed used by pygolang only on Python3

nexedi/pygolang@cd67996e

and with Python2-only testing I missed to handle it.

-> Fix it and add test for pygolang/py3.

/reviewed-on nexedi/slapos!864

Tests added:
- connexion parameters
- monitor url
- slaves instanciation

Adds connexion parameters:
- ipv6
- port
- ipv4

Upgrade dnspython from 1.15.0 to 1.16.0

Removes unused parameters in instance-powerdns-replicate.cfg.jinja:
- private-ipv4
- public-ipv4
- domain

This reverts commit 5d46a499.

Changes to "fix argument parsing" (to allow passing argument containing space)
had a regression that backslash characters are escaped.

Let's go back to slapos.toolbox 0.112 for now.
