Use cluster's hvparams in LUInstSetParams
Since the instance does not have hvparams at that point,we have to use the cluster's hvparams here. This fixesa crash when using 'gnt-instance modify'.

Inline simple "alias" variables
Remove variables in the form "var = self.var" throughout all LU's. Those"alias" variables make it harder to read the code (it's no longerimmediately clear what's a field and what's a local variable), and canintroduce subtle bug (especially when not used consistently and when...
Index nodes by their UUID
No longer index nodes by their name but by their UUID in the clusterconfig. This change changes large parts of the code, as the followingadjustments were necessary: * Change the index key to UUID in the configuration and the ConfigWriter, including all methods....
Use hvparams in GetInstanceInfo
This patch extends the GetInstanceInfo function of thehypervisors by an hvparams parameters. This leads toan extension of the instance_info RPC call and theadjustmend of all classes using this call.

Add disks_active to configuration
This flag tracks if the disks of an instace are supposed to be active.That's the case when an instance is running or when its disks gotactivated explicitly (and in a couple of other cases).It will be used by watcher to re-activate disks after a node reboot....
Spindles are mandatory with exclusive storage
If they are not specified in the command line an error is reported. Also,disk creation would fail without them.
QA has been updated.
