Use cluster's hvparams in LUInstSetParams

Since the instance does not have hvparams at that point,
we have to use the cluster's hvparams here. This fixes
a crash when using 'gnt-instance modify'.

fail.

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...

Convert node indices to UUIDs in configuration

cfgupgrade replaces the occurences of node names (where they are used as
index) with the node UUID.
It also supports the inverse replacement, so downgrades are supported
too.

Tests for cfgupgrade are adapted as well....

Index nodes by their UUID

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
adjustments were necessary: * Change the index key to UUID in the configuration and the
ConfigWriter, including all methods....

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...

Support VNC binding to an interface

Currently, the VNC bind address can only be specified as an IP
address. Given that this is a cluster-wide parameter, there
aren't many sensible choices besides 127.0.0.1 and 0.0.0.0. This
patch allows to also specify it as the address of a specifed...

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...

hv_xen.py: make hvparams mandatory, remove fallbacks

This patch removes the fallback to the xen command from the
auto config and adds an exception instead. Also, the
hvparams parameter of the functions GetCommand, _RunXen and
_GetInstanceList are made mandatory....
