Add support for 'offline' nodes

This patch drops compatiblity with Ganeti 1.2 and adds support for
offline nodes in the cluster. When reading from RAPI, the drained nodes
are considered offline so that we don't allocate on them too.

Update all needed node fields on f_mem change

This fixes the setFmem function which didn't compute other related
fields after free memory change. Ideally, this should be abstracted so
that add/remove Pri and similar functions could reuse it instead of
duplicating code.

Fix interaction between down instances and nodes

If an instance is down, it's memory is not reflected in the node used
memory, and thus the node free memory is higher than the actual value.
This patch deducts the memory for such instances from the node free...

Show the x_mem/i_mem in node list

This patch adds checking of cluster data in the binaries and display of
node's x_mem/i_mem in the node list.

Add a new node filed x_mem

Nodes can have some memory unaccounted for, due to (e.g.) hypervisor
overhead, rounding errors in reporting, etc.

It is better if we model this memory explicitly instead of hiding it,
and actually since the n_mem addition it is actually required to do so....

Remove unused and obsolete function

The Node.str function is very old and is not useful since the node
objects have much more fields today. This patch removes it, and if
needed a full node display can be done via ‘show’.

Add node memory field to Node objects

This patch adds a new n_mem field to the node objects, and implements
read/save/show support for it. The field is not currently used (except
in the node list) but will be used for checking data consistency and
instance up/down status.

Pass actual types to node/instance constructors

This patch changes the parameters passed to the node and instance
constructors from generic Strings (which are then parsed via “read”) to
the actual used types, by converting them earlier in Cluster.loadData.

Some small changes in preparation for hscan

This patch does some small changes:
- fixes a comment
- export more node functions (unneeded now, but hscan will use them)
- fixes Makefile rule for building the programs

Show offline nodes in the node status list

This patch adds a new ‘-’ flag for the node status which denotes offline
nodes.

Add a new 'offline' Node attribute

This patch adds a new node attribute - offline - which will serve to
skip nodes from the target candidate list.

Introduce a namespace for the modules

The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, in
compliance with standard practices.
