Add a test for hsqueeze expansion

In this example, there are 7 nodes, each with capacity for
4 instances. Two nodes are online and host 4 instances each,
thus forming a cluster with no free resources. Four additional
nodes a standby, and two additional node is offline for other...

Add test for hsqueeze compression

In this example cluster, there are 6 nodes with
capacity for 4 instances each, holding a total
of 8 instances. So even after turning off 2 nodes
and rebalancing, every node still has capacity for
2 instances.

Add shelltest for the --ignore-dynu option of hbal

In the example, we have two nodes and 6 instances, all using external
storage. There are four small instances on one node, and two big
instances, requiring twice the amount of resources of a small instance,...

Add htools shell test for VCPU handling

This tests that VCPUs used by both instances and node OS are correctly
accounted in allocation.

Load CPUs used by the node OS in htools

A new field is added to the Node type, and it's used to initialize the used
CPUs field.

The signature of Node.create has been split among lines to match the
parameter list.

Add test for the --full-evacuation option

In this example cluster, there are four pairs of nodes, each hosting
two instances. Each node has disk capacity for an additional instance.
Therefore, for normal online rolling reboots, there are two node groups,...

Add test for shrink heuristics over different resources

In this example, memory prevents adding more than one instance on
the first node. Yet, on the other nodes, 2 instances can be placed
each, if disks are shrunk appropriately. This, however, requires
to courageous decision to shrink disks next, even though more nodes...

Add a test for hspace to respect instance policy

In this example, the instance policy for disks prevents allocation
of more than one instance per node. The test verifies that tiered
allocation still respects this and doesn't attempt to place policy
violating instances on the cluster....
