htools: fix potential bug in ialloc/change-group

Currently, the ChangeAll mode of nodeEvac computes the primary group
of the instance and then uses the resulting group index for computing
the group score. However, during the change-group operation (which...

htools: run IAllocator input through checkData

As the IAllocator backend is using a different data path than the
others, it doesn't get the full functionality that loadExternalData
does. This results in the current situation where checkData is not run
on the input cluster state, which means the node memory properties are...

htools: abstract a function for displaying warnings

This will make it possible to reuse this in IAllocator too.

htools: return the final instance map in ialloc

Similar to the previous patch, this returns the final instance map
from the iallocator run, which will allow saving the cluster state for
further examination/post-processing.

htools: implement post-alloc cluster status display

This patch changes the IAllocator result formatting workflow to return
the final node list, which can be then used to display the final node
status too—currently only the initial status can be shown, which is...

htools: return new state from new IAllocator modes

The old modes already return the node list (as part of AllocSolution),
this patch makes the new modes provide this new information.

htools: update the node-evac/change-group result

… per the new design changes. This also requires changes to
updateEvacSolution, as passing in the original instance is not
helpful; we just pass the instance index now and look up the actual
instance in the modified instance map....

htools: add change-group IAllocator mode

This builds a lot upon the node-evacuation mode, and its
implementation is therefore quite easy (once node-evac was added).

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....
