While testing this merge request : erp5!243

The following test was failing for me : https://nexedi.erp5.net/test_result_module/20180107-664D9A6/13

Since numpy is not added as a dependecy for h5py. the testnode didn't upgraded numpy while upgrading h5py. 
Adding numpy as a dependency should fix it

Fixes all cloudooo being given the same port, because of jinja2 variable
scoping.
Also, move to buildout.hash.cfg for md5sum maintenance ease.

Also update README accordingly.
Its becasue now erp5-site is being created automatically using software-type
default and there is no create-erp5-site software-type anymore.

In the particular case of PATH, '' is the same as '.',
which is a bad idea from a security point of view.

fontconfig > 2.12.1 now requires gperf.

This reverts commit 38123b86.

fontconfig was not building any more on many machines (most testnode machines). Revert
until investigation is done.

This fixes part of resiliency tests

( because  allow-picked-versions require all versions to be pinned )

Since erp5 commit "[taskdistribution] Drop needless TaskDistributionTool"
the tool is not available anymore and only TaskDistributor shall be used

It provides fix to call correct endpoints (Distributor instead of a Tool).

Issue was:
- user project_user was created
- project_user create stored routines
- mysql data is dumped (including list of users)
- mysql data is restored, but stored routines have the information
  DEFINER that must match an existing user. This does not
  work if there is no flush privileges instructions

So make sure to insert flush privileges while dumping

This reproduces what happens on a Prod system, where
TokuDB turned out to use much more CPU than FileStorage.
