with python 2.6 support that can be still required for initial setup of SlapOS.

even though there are install_requires and setup_requires...

Let the supervisord of slaprunner managing the instance processes
be managed by supervisord of slapos node.

Fixes problems of process like supervisord escaping control.

Also remove unused variable in nginx-conf.

Also unpin slapos.Cookbook.
Related problem with Jinja2.7 has been fixed in slapos.recipe.template 2.5.

Informations about what failed and what succeeded.

Side effect: activate binlogs.
current backup system does not work.

+ make promise checking this

Import script of webrunner asks stop of all instances, runs slapos, runs
consistency checks, runs scripts, ask start of all instances.

Allows HOME to be easily referenced in some cases where buildout:directory is not available.

Allow to lint/edit/develop more easily the bash script without having tons of template parameters.

slaprunner: concatenate exporter.exclude file of each partition of the runner and write it in the standard location.

Allow to exclude things from inside of the runner's partitions without knowing what instance it is.

This permits invoke custom code after copy the instance to the right location [Working in progress for better restauration]

  By using more them one, it fails during the compilation.

  Missing update on parts, slapos-repo needs to be explicitly invoked.

It was applied by the combination of [slapos-repo] that checkouts master
branch and [slapos-repo-config] that checkouts
$${slap-parameter:slapos-software} branch afterwards.
When instance profile runs for the second time, [slapos-repo] resets to
master and [slapos-repo-config] does nothing.
This fix consists in using directly $${slap-parameter:slapos-software}
in [slapos-repo].

[slapos-repo-config] was also setting up .project, this is still the
case and the section was renamed to [instance-software] for
consistency.
