create(drop) node(group) pushed

this friday.

no (currently :) known bugs

end of think-period

today, I think I finally cracked how to create(drop) a nodegroup.
basic concept is to
- temporary block gcp
- create(drop) the node group
- unblock gcp

(the same concept is btw used for adding a starting node to gcp)
the block should last for micro seconds

now it's only implementing it...

---

very happy that I now know how to proceed,
I've spent quite a lot of time trying to figure out a 100% safe
way of doing it...(wo/ blocking gcp)
but this solution will be efficient and fairly easy to implement.
(if any protocol dealing with (multi)node-failures can be considered easy)
