Opcodes: move storage type checks to cmdlib

So far, there was a static check whether or not a given
storage type of an opcode was enabled. This check is
no longer possibe at this layer, because the information
whether or not file/shared file storage is enabled must...

Improve handling of storage info

This patch improves the processing of storage information
as result of the 'node_info' call in the following way:
- It removes the override for LVM storage. This was needed
in MakeLegacyNode info to be compatible to the...

Make names more descriptive

LUGroupVerifyDisks had some not very descriptive names which made it
hard to read and understand the code. This patch renames some methods
and variables to make it more readable.

Also, the return type of MapInstanceLvsToNodes was changed to contain...

Extend RPC call 'node_info' by storage parameters

This patch extends the actual RPC call to accept storage
parameters with each storage units. It adjusts all code
which performs this code by integrating the 'exclusive
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
config. This change changes large parts of the code, as the following
adjustments were necessary: * Change the index key to UUID in the configuration and the...

Fix wrong assert

An assert wrongly verified that the node name instead of the node UUID
is in the set of locked nodes. This patch fixes this.

Refactor NodeInfo RPC regarding storage reporting

The NodeInfo RPC call is refactored to handle now more than
just storage reporting for volume groups.

Since NodeInfo now returns storage space information not
necessarily for volume groups, but also for other storage...

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...

Remove XEN_CMD from constants, adjust to PowercycleNode

This patch extend the RPC to powercycle a node by a
hvparams parameter. This parameter is used by the
xen hypervisor to determine which xen command to use.
The respective LU is adjusted as well.

Since this was the last operation depending on the...

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...

Verify: node info and instance list

This patch enhances node verification by:
- Factoring out the verification of the node info
and the instance list to increase testability.
- Make both of them use the hvparams parameter.

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....

RPC 'node_info': <storage_type,key> instead of vg_names

This replaces the field 'vg_names' in the RPC call of 'node info' by
'storage_units'. A storage unit is a tuple <storage_type,key>
