Needs migrator to add <DISK_ACTUAL_SIZE> <DISK_VIRTUAL_SIZE>
Needs to update Sunstone views for accounting

Added <DISK_COST> to <SHOWBACK_RECORD> it may require migrator.
Sunstone needs DISK_COST in templates.

Currently DISK_ACTUAL_SIZE is used as a place holder, but DISK_VIRTUAL_SIZE can be used also. Moreover we need to deal with situation where snapshosts are removed within the same history record window. Probably, either add a new record (as we do for attach) or if snapshoting remains only for poweroff that will add the record.

Probes needs to use the same names, and use for known/required information:

POLL_ATTRIBUTE = {                                                                                           :usedmemory  => "USEDMEMORY",                                                                            :usedcpu     => "USEDCPU",                                                                       
        :nettx       => "NETTX",                                                                         
        :netrx       => "NETRX",                                                                         
        :state       => "STATE",                                                                         
        :disk_actual => "DISK_ACTUAL_SIZE",                                                                      :disk_virtual=> "DISK_VIRTUAL_SIZE"                                                                  }

:nettx => "NETTX",

New parameters:

DISK_SIZE = [ ID=<disk_id>, SIZE = <actual_size_in_mb> ]
SNAPSHOT_SIZE = [ ID=<snapshot_id>, DISK_ID=<disk_id>, SIZE = <actual_size_in_mb> ]
TOTAL_DISK_SIZE = <sum of the sizes of all disks and all snapshots in MB>

Use this ticket to update these VM probes too:

USEDMEMORY => MEMORY
USEDCPU => CPU
