Reduce shebang length to allow developping inside a runner.

Instead, of that, the notifier wrappers will run the scripts several more times in case of failures
This is better than silent failures.

  Introduce NGINX on the same partition of apache to handle websocket\
  and eventsource types.

  The NGINX will run on another port and it would require a second ip at
  the machine for enable it.

  This configuration is a working version with fully https support, but
  some additional adjustments might be required.

  Use a single apache server to handle cache and normal apache configurations. With trafficserver,
  the access would follow the model:

    Apache > Traffic Server > Apache 'Cache' > Backend

  Now the configuration changed to:

    Apache > Traffic Server > Apache (same as before) > Backend

  This simplify the amount of apache process to manage on the frontend.

  Reduce a bit the number of sections also for create directories
  Move all 'set's and 'do's to earliest as possible, to keep buildout syntax more evident
  Drop duplicated logics and 'if's reducing general code

because zope.interface is not required to build rebootstrap python.

This reverts commit ae808179.

Reason for revert: zodbtools depend on ZODB while currently neoppod &
erp5 are depending on `ZODB3 = 3.10` so upon installing both ZODB3 and
ZODB are installed. Together with our requirement

    stack/erp5/zope-versions.cfg:transaction = 1.1.1

This creates version conflict and installation fails:

2016-11-17 14:56:35,858 testsuite    : INFO     slapgrid_sr : 2016-11-17 14:56:35 slapos[3698] INFO The version, 1.1.1, is not consistent with the requirement, 'transaction>=1.6.1'.
2016-11-17 14:56:35,937 testsuite    : INFO     slapgrid_sr : 2016-11-17 14:56:35 slapos[3698] INFO While:

So revert zodbtools hooking for now until we upgrade our ZODB to ZODB > 3.

As advised by @Tyagov this adds zodbutils egg [1,2] to our software
stack: both NEO and ERP5 (since stack/erp5/ inherits from
neoppod/software-common.cfg)

I have not build-tested this patch but I hope it should be ok.

*  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

This reverts commit 2b0c61d9.

Reading the .installed.cfg file is not the correct way of storing values. The publish_early
recipe should be used instead

This reverts commit 8787716d.

repositories if configured are public. Thus such a check will by design fail.

@seb, @rafael  please review. I tested this and it works.

Then we'll upgrade setuptools for everyone at the same time as we switch to
zc.buildout 2.x

Same issue of avoiding publishing private code, this time with nothing published by default.

Ivan, can you quickly try this apache config and give your opinion if it acceptable that you add .htaccess in the code to be tested ?
