account, and disk 0 is added twice.

HTS_USE_VNC, rename and remove KVM

Currently we use the HTS_USE_VNC constant only to copy the vnc password
file. While KVM uses vnc it currently has no password support, nor we'll
be on time making one for 2.0, so renaming the constant to
HTS_COPY_VNC_PASSWORD and only putting Xen HVM in it. In the future...

Some fixes to node add and re-add

The patch changes the pre-checks in node-add and re-add:
- if the node is not already in the cluster, refuse to re-add
- when re-adding, reuse the secondary IP from the cluster
- when re-adding, reset the offline and drained flags, so that RPC...

Instance parameters: force typing

We want all the hv/be parameters to have a known type, rather than a
random mix of empty string, boolean values, and None, so we declare the
type of each variable and we enforce/convert it.

- Add some new constants for enforceable value types...

ConfigWriter: handle the drained node flag

This patch changes the master candidate pool computations in
ConfigWriter to properly handle drained nodes. They are now excluded
from counting towards the reachable number of candidates.

The patch also adds verification of consistency for the node status....

Allow query of the drained node attribute

This patch exports the drained attribute:
- LUQueryNodes accepts now the drained field
- RAPI exports it for node objects
- gnt-node info shows it now (along newly-added master_candidate and
offline flags)...

Add a ‘drained’ attribute to node objects

This attribute will be used to prevent any allocation on the node (any
of replace-disks with new secondary this node, failover to the node,
migration to the node).

The patch adds the attribute and initializes it correctly in cluster...
