This patch series reworks gnt-node evacuate to do (if early release is enabled) a parallel evacuation of nodes.
We do this via a new IAllocator request type, and via a new opcode/lu. gnt-node evacuate runs this new opcode, gets the list of (instance, node) new preferred locations, and then submits N jobs, one for each instance. I kept the 'destination node' functionality, but it complicates the code quite a bit. If we were to remove that, we could simplify the LU (the gnt-node code is not affected by that). Note that there's a set of patches on the htools project that implements the new iallocator request type; I'll release a new version of that project before 2.1.1 will be released so that people can upgrade separately.
