Move the disk size computation to its own function

This is currently hard-coded for the two drive case and will need to be
reworked for multi-disk support.

The patch is needed to support passing the total required size to the
iallocator interface.

Verify: add N+1 Memory redundancy verification

For every node we check that we can host all the instances it's currently
secondary for belonging to the same primary. This ensures that if a node fails
all its instances can fit on their secondary node. The code only works when...

Verify: save instance config

Save the instance config after we queried it in an instance_cfg dict. This can
be used later by any function that wants it, without reloading it from the
configuration module. It will be used for N+1 memory resilience checking....

Verify: add more instance information to node_info

The sisnt-by-pnode field contains all secondary instances of a node, grouped by
their primary node. This information allows us to see quickly if when a node
dies some of its instances cannot be started on their secondary node....

Verify: add instance information to node_info

With this patch node_info is changed to store information about which primary
and secondary instances are configured on a node. This information is useful to
check memory and disk allocation. A list of non-redundant instances is also...

Verify: Add and populate node_info dict

During information gathering we collect information from call_node_info, and
then when we cycle trough the nodes add it into a node_info dict containing a
node's free memory and disk. This will be useful later to verify that the...

Rework the results of OpDiagnoseOS opcode

Currently, the opcode DiagnoseOS is the only opcode that return a
structure of objects.OS (which is a custom class, and not a simple
python object) and furthermore all the processing of OS validity across
nodes is left to the clients of this opcode....

Change client protocol to raise exception on failures

Currently the luxi.client.SubmitJob and Query methods return the unserialized
result without processing it at all. This patch changes this by adding a
'RequestException' error that is raised if the query itself or the...
