Add a way to takeover remotely.

Why having wrappers of wrappers of wrappers, when we can have simple, readable code?

Used to access directly to VM.

Was tunnelling to the wrong port.

First move to a clean KVM wrapper. And must faster maintenance/feature adding.

Doing fast&dirty code is nice, but only if you don't maintain the code yourself.

Note: Duplicates code, and heavy use of recipes.

No need for external NBD by default. No need to wait minutes to boot from installer in VM.

It is in slapos 1.0 itself.

Resilient stack: Experimental: dynamically forward instance parmaeters to requested export instance.

Not stable yet.

Bit of cleanup about now useless backward-compatibility.

So that it doesn't change every day.

So we remove the trailing /.

2.7 is not backward compatible and breaks import-list.

More logical. Also add comments.

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.
