htools: add group restrictions to findBestAllocGroup

While a normal multi-group allocation doesn't need to restrict the
list of target groups beyond the unallocable status of some groups,
when we relocate instances from one group to the other we need to
limit the subset of searched groups....

htools: generalise and rename availableLocalNodes

Currently this function works in the context of an instance, computing
its local group nodes. We can use generalise it to take a group index
argument, so that it's not bound to an instance, and we rename it...

htools: add ChangeGroup to IAllocator types/loader

This patch updates the types and functions in IAllocator.hs and
Loader.hs to the new design changes (elimination of multi-relocate
mode and replacement with change-group).

It also removes an extra re-export of EvacMode from Loader.hs....

htools: split tryMGAlloc in two

Currently, this function does both identify the best group for an
instance, and format the results (partially). The former functionality
is useful in other contexts too, so let's split the function in two.

htools: add node-evacuation of DRBD all nodes

This is much more complicated than either change primary (which is
trivial) and change secondary (which is also simple).

The main strategy is:

- choose a new secondary (that will become the final primary) and...

htools: small optimisation in Cluster.collapseFailures

This makes fewer temporary data structures, and thus brings a bit of
improvement in total runtime.

htools: add optional limit to allocation count

Currently, the tieredAlloc/iterateAlloc functions will not return
until the allocation fails; this means unit-testing their
functionality (e.g. that an instance can be allocated) is slow, since
they will allocate all possible instances....

htools: rework compCV so that we can use [Node] too

In some cases, we have a [Node.Node] list, instead of a Node.List
structure. Instead of converting [Node.Node] to the latter, let's
rework compCV and add a compCVNodes such that we skip this
(potentially expensive) step....

Adding a wrapper around connecting to kvm console

The wrapper will connect to the console, and check in the background if
the instance is paused, unpausing it as necessary.
