[Ovirt-devel] Enumerating node information to the WUI

I've been looking at some system details that might be of interest to 
the WUI/admin when deploying virtual machines.  Particularly, I've been 
looking at CPU, memory, disk and network details, though there may be 
other elements that we'd want to pull from the managed node as it's 
coming up. At any rate, what would seem to be of interest are:

CPU: the family, model, cpuid level, cache size, number of cores and the 
set of CPU flags. This would give us a nice idea of the individual CPU's 
capabilities.

As a result, we'd want to refactor the hosts table a bit. Rather than 
capturing as a column the number of CPUs, we could get that implicitly 
by having a record-per-cpu for the host. Then each row would capture the 
important details from above.

MEM: We currently return the total system memory reported but should 
probably also grab the free memory after the managed node image is loaded.

DISK: Returning the physical and logical partitions with free space 
available.

NETWORK: Iterating over the physical interface adaptors. Also returning 
any IP addresses already assigned and routing information.
