(2.13) Let drbd disks resync during cluster verify

Commit 9b0e86e issues an error during cluster verify if the status
of DRBD is degraded and if the local disk is not UpToDate.

Still in case of a newly created instance or a newly attached disk with
--no-wait-for-sync, if a cluster verify runs it will report errors...

(2.13) Export logical_id info to hooks env

..and let utils compute the hooks environment related to disks.

Until now, the only exported information regarding disks in hooks
context was their size, mode, name and uuid.

With this patch, depending on the disk template, we export the info...

(2.13) Allow NICs with routed mode and no IP

..in case attached to a network.

This allows us to define an IPv6 only network (currently with a
dummy IPv4 subnet) with connectivity mode 'routed' and let a NIC
inside this network have only an IPv6 address, e.g. an...

(2.13) Pass the access parameter to ExtStorage template

Add the ExtStorage template to the set of templates that accept the
'access' parameter. The default 'access' of the node-group for
ExtStorage devices will be 'kernelspace'.

Update the man page for gnt-instance to state that ExtStorage templates...

(2.13) Handle IDISK_ACCESS parameter in ComputeDisks

The IDISK_ACCESS disk parameter was not handled in the 'ComputeDisks'
function, thus the 'access' parameter was ignored during the instance
creation. This patch fixes this and also fixes a typo in
'_VerifyDiskModification'....

(2.13) Make 'access' an optional disk parameter

This patch makes 'access' an optional disk parameter just like
spindles, mode, name, vg and metavg. This option can only be set to
'kernelspace' or 'userspace'. When 'userspace' is used, the instance
will access this disk directly without going through a block device....

(2.8r) Workaround for Issue 621

Upon LUNetworkDisconnect() and LUNetworkConnect() try to acquire
all cluster's instances.

By that _LS_ACQUIRE_ALL acquire mode is set and not
_LS_ACQUIRE_EXACT and thus the deleted lock does cause any problem.

NOTE: This workaround is not merged upstream. They prefer to have...

Fix DRBD version check for non VM capable nodes

Commit 742dc8de revealed a bug concerning DRBD version check during
cluster verify: In case non VM cabables nodes have DRBD not
installed, we get a version mismatch warning.

VerifyNode() updates the NV_DRBDVERSION key in the response message...

Renaming NV_VMNODES to NV_NONVMNODES

This patch renames the constant 'NV_VMNODES' to
'NV_NONVMNODES' as it is actually used to store
a list of non vm-capable nodes.

Node names in NV_VMNODES

This patch populates the list 'NV_VMNODES' with node
names and not node UUIDs, as the backend only uses this
list to identify VM-capable nodes by querying for the
node name.
