This is required starting erp5.utils 0.4.51

Also add a missing md5sum for instance.cfg.in

Follow changes in erp5.util that will allow for stable test lines.

As sources URL depends on the branch, update it to correct one.

Based on caddy-frontend tests

Filename is split as an URL path, and joined in OS-dependent manner.
Remove corresponding comment in all buildout.hash.cfg files.

Extended KVM SR does not have this hosts in allowed, and we need to stick
with it.

For reference in case if some existing Python distribution does not install,
it was detected with "git diff 8deeab.. -- stack/slapos.cfg"

For supervisord AF_UNIX socket

This is a convention from

To run tests from software/proftpd/test

Depending on host python version the string "Build successful" renders
differently, so do not be too smart for it and simplify it.

In order to track issues with software deployed in VM, provide more
introspective information about the VM itself.

It is not needed to follow KVM development blindly and be hit by
bugs during the development.

 zc.buildout version up to 2.5.2+slapos012
 slapos.recipe.template version up to 4.3
 slapos.core version up to 1.4.4

This is useful to being able to peek for low level site result details.

This fixes part of resiliency tests

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).

Without logs of SlapOS it is hard to understand the problem in case of
failure, thus add part of this information into log file.

  If someone is developing an erp5 test node inside a webrunner, there is no reason to put entire data on resilience.

Pin erp5.util to version 0.4.49, with:

 * process timeout
 * xmlrpclib.Binary wrapping

  In order to make an resilient backup, resilience stack wait for the internal backup finishes,
  before proceed to notify the pbs. This commit keeps the default behaviour (wait for 10 min w/o changes),
  however allows test software release adopt a much shorter waiting time (1min).

  With this commit we can accelerate resilience tests in several minutes.

  Allow set software-root via parameters allow the webrunner inside a erp5testnode,
  recover the the previous builds from previous resilient tests, and only update (instead build from scratch)
  This is a typical usage on the webrunner (keep updating SR), so there is no
  problem on use this approach on erp5testnode tests.

Software release for testing deploy scripts and Ansible playbooks
provided in slapos.package repository.

It is used by Test Suite and ERP5TestNode and runs tests configured in
Test Suite against VM built with deploy script.
