Add cleanup parameter to instance failover

Most of the code is shared with instance migrate, so we actually only need
to add the parameter and pass its value along the the common code.

Also, tests and harep are updated to support the right set of options to...

Support big-step shrinking in tiered allocation

In tiered allocation, if by shrinking only a single resource a valid
allocation can be found, shrinking is bound to shrink on this resource.
Of course, after shrinking that resource a little bit without finding...

In tiered allocation, cut non-promising shrinking tries

The heuristics for tiered allocation has been improved in that it
chooses to shrink such a resource next where by shrinking only this
resource a valid allocation can be made, if such a resource exists....

Improve hspace shrinking strategy

In tired allocation, hspace shrinks that resource of the instance
next, that causes failure on most nodes. While, this is not a bad
strategy in general, it can lead hspace into a dead end if for a large
number of nodes a particular resource blocks any further allocation of...

Make shrinkByType aware of individual disks

When shrinking an instances, you can't just get smaller disk footprint
while leaving the individual disks as they are. Make the shrink
heuristic aware of that fact, and decrease all individual disks as
well. Fixes issue 484....

Add tests for network-aware allocation

hail-alloc-invalid-network defines a cluster with two nodegroups and an
allocation request which does not fit on any of the groups. Group 1 has
invalid disk-templates while Group 2 is not connected to the right
networks....

Honor network connections in hail

Before trying to allocate nodes in node groups, node groups are now
filtered based on the networks they are connected to an the networks
which are required by the new instance.

Parse NIC data from allocation request in hail

Add a NIC type and extend the Instance type by a list of NIC's. Parse
the NIC's in allocation requests and store them for now. Later patches
will make use of this field in order to ensure that the requested
instance is only placed in node groups wich are connected to those...
