Test for hroller taking non-redundant instances into account

The example cluster consists of 6 nodes, each hosting 2 instances and
having capacity for 3. So, while the drbd-induced graph consists of
only insulated nodes, no more than two nodes can be rebooted at the...

Add a test for online rolling reboot scheduling

In the example configuration, the graph constructed by just connecting
primary and secondary instances is two-colorable. However, when taking
conflicting locations of secondary nodes into account, three reboot...

Add a test demonstrating the --node-tags option of hroller

The example is a cluster of 6 nodes, paired into 3 group by three
instances. So the whole cluster would need two reboot groups. The two
tags select, in two different ways, one node of each group. So, when...

Add multiple min/max specs in instance policy

Now instance policies can contain more than one min/max specs. This is the
main element of the "Constrained instance sizes" section in the
"Partitioned Ganeti" design doc.

This is a big patch, but changing the type of a configuration item requires...

Add unit tests for hroller

Add a unit test for hroller in a situation where the order
is completely determined. There are 3 nodes where node 2 has,
for each of the other nodes, an instanced shared with it. So
node 2 has to be a reboot group of its own. There are no more...

Adapt test data to changed ipolicy format

The test data for hail allocating a multi-disk instance was
originally added in the 2.7 branch. On master the format
of the ipolicy had changed; "min" and "max" are no longer
top-level of the ipolicy, but instead below the "minmax"...

Add shelltests verifying hail applies disk ipolicy per disk

We test on two minimal examples, a positive and a negative one, where
the possibility to allocate a node depends on whether the disk policy
is checked on a per-disk level or on the total amount of disk space...

Refactor ispecs in ipolicy structures

Minimum and maximum instance specs are put together into a single element
of the instance policy. This is in preparation for introducing multiple
min/max specs.
