xend: add a description config item for each guest.

Add a new option "description=" to each VM to increase the
manageability of VM, which could be accessed via "xm list -l
MACHINE".e.g add "description='(name, james),(priority 5), (owner
james.song@company.com)'" to configure file, User can get the VM's
attribute easily by "xm list -l Machine" or some tools.
