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....

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...

Export connected networks to IAllocator

IAllocators should not put instances on nodes in nodegroups which are
not connected to the network the instance should be connected to.
Therefore, export the networks a node group is connected to to the
IAllocator, so it can account for this restriction....

Re-activate previously active disks in watcher

The watcher process previously (incorrectly) examined the admin_state
field to figure out if the disks of an instance should be activated
after a node reboot. This is changed to use the disks_active field of...
