KVM: use cache=none for shared disk templates

Disable host cache for externally mirrored disks to avoid cache incoherency.
Without this, migrations between the same two nodes may end up in disk
corruption.

This is a runtime override of cluster defaults, mostly a workaround....

Shared storage instance failover

Modify LUFailoverInstance to enable shared storage instances to failover.
Shared storage instance failover requires either a target node or an
iallocator to determine the target node. If none is given, the cluster default...

Shared storage node migration

Modify LUNodeMigrate to provide node migration for nodes with instances using
shared storage. gnt-node migrate has to be passed an iallocator for migration
of shared storage instances to be performed. When using a shared storage...

Shared storage instance migration

Modify LUMigrateInstance and TLMigrateInstance to allow instance migrations for
instances with DTS_EXT_MIRROR disk templates.

Migrations of shared storage instances require either a target node, or an
iallocator to determine the target node. If none is given, the cluster default...

CLI changes to facilitate shared storage migration/failover

Add DST_NODE_OPT to cli.py to use for directly specifying the target node
during migration/failover.

gnt-instance failover/migrate also get passed an iallocator option.

gnt-node failover/migrate get only a target_node option....

Migration and failover: add iallocator and target_node slots

Add iallocator and target_node slots to OpMigrateInstance and
OpFailoverInstance to facilitate shared-storage-backed instance mobility. Add
iallocator slot to OpMigrateNode (no explicit target_node in this case)....

IAllocator changes to work with shared storage

Make cmdlib.IAllocator shared-storage-aware. IAllocator requires secondary
nodes only on DTS_NET_MIRROR disk templates and requires no secondaries for
DTS_EXT_MIRROR templates.

Shared block storage support

This patch introduces basic shared block storage support.

It introduces a new storage backend, bdev.PersistentBlockDevice, to
use as a backend for shared block storage. The new bdev requires a new
BLOCKDEV_DRIVER_MANUAL constant with the value "manual" and uses it as...
