This library is required for a generic implementation of OAuth implementation of facebook login

  The version 0.4.0 uses an deprecated version of 
  GraphAPI which might not work anymore.

  Apply commits:
   stack.erp5: Drop unneeded executable permissions. (fe7ea950)
   stack.logrotate: Fix support for stopped processes.
   stack.erp5: Use an iterator to produce port numbers.
   software/erp5: if wendelin-core-zblk-fmt is not given, then use wendelin.core's default.
   software/erp5 & stack/erp5: Add a new parameter wendelin-core-zblk-fmt.

When originally in 0a446263 (ERP5 and Jupyter integrated together) I added
Jupyter support into ERP5 the parameter for whether to enable/disable it was
declared as boolean in JSON schema but processed as string in instance code,
this way preventing usage of real JSON's boolean.

Fix it.

(also fixing up software/slapos-master/ which copied the files for play in 87d13789)

  This changes were squashed into a single commit and it includes:

    - install slapos_configurator by default
    - Allow define ssl authentication for a certain zope family
    - Allow define custom zope path per zope family

  Those changes are originally written by Alain Takoudjou and rewrited by Rafael Monnerat

  The local changes are not yet generic enough to be shared among stack, so
  Introduce local changes here better

Those customization do not work anymore and it is preventing tests to run,
 so it should be reintroduced later in a way it works.

lab.nexedi.com is now our main domain for git hosting.
lab.nexedi.cn continues to work for backward-compatibility reasons.

slapos.core.git moved to lab.nexedi.cn and repository on git.erp5.org
made readonly. Update all referenced to old repository location:

New 'slapos-kill' from slapos.toolbox is used instead of 'killpidfromfile'
This is required for NEO which does not write any pid file.

Also put back certificates on software release url.

This is the only remote url which is going to be trusted outside of buildout.

Fetching list of keys over the network from non signed url has no sense.

All ERP5 profile is now in a single place.
Moreover, use slapos.cfg stack.

Also, stop referencing reference implicitly pulled parts.

Parameters are not final yet, and must evolve to get something resilient to
frontend "movements" (ex: frontend machine dying and frontend being
re-allocated on another, or frontend being replaced by an instance from
another software release - as it will happen for upgrades).

Modifed from original version by Rafael in order to fix conflicts
on md5 of the files and changes on same file done in multiple branches.

All Products that are not packaged as python distributions need to be placed into a "Products" package since ZEO might need to be able to import them anyway.

Also, as backward compatibility is not needed at this level, implement what
is requested in BBB comment.

This reverts commit a26dcf05.
