Nettle: requires m4 component.
qemu component: update conditional sections to buildout2-style.

s.r.cmmi 0.2.0 switched to buildout2-style, so we follow.
In the meantime, use a fixed target-list if it proper conditional
section is not supported.
KVM SR: move [template] upper

More logical. Also add comments.
Resilient stack: add missing extends and parts
Resilient stack: use Jinja2.6

2.7 is not backward compatible and breaks import-list.
Resilient stack: explicitely list parts for pbs import/export.
Resilient stack: notifier-url is rather a notifier-host

So we remove the trailing /.
SlapOS Stack: pin setuptools

So that it doesn't change every day.
KVM SR: set more logical section name for params publication.
KVM SR: Remove explicit "slap-connection" in instance.

Bit of cleanup about now useless backward-compatibility.
KVM SR: add resiliency support
