Extend RPC call 'node_info' by storage parameters

This patch extends the actual RPC call to accept storage

storage' flag into the lvm storage unit....

Index instances by their UUID

No longer index instances by their name but by their UUID in the cluster

adjustments were necessary: * Change the index key to UUID in the configuration and the...

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 longer
immediately clear what's a field and what's a local variable), and can
introduce subtle bug (especially when not used consistently and when...

No longer index nodes by their name but by their UUID in the cluster
config. This change changes large parts of the code, as the following

Add cluster name to instance migration RPC

This fixes a 'FIXME' in the xen hypervisor. The instance
migration requires the cluster's name. This should come
from the RPC call, but so far was hackishly taken from
ssconf. Ssconf is intended to be used by scripts only and...

Adjust all callers of RPC 'call_node_info'

This patch contains all adjustments necessary to code that
uses the 'call_node_info' call. The adjustment is necessary
because the call's signature changed from receiving a list
of hypervisor names to a list of tuples...

rpc / noded: add hvparams to instance_list call

The 'instance_list' call needs to be extended to accept
hvparams. This is one of the few RPCs where it is
necessary, because there is no instance given whose
hvparams could be reused.

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 got
activated explicitly (and in a couple of other cases).
It will be used by watcher to re-activate disks after a node reboot....
