Hammer CLI

The --compute-attributes option when creating a host on a Libvirt provider accepts a "memory" key, which currently has to be indicated in bytes.
This is awkward for common memory amounts; please allow specifying the memory size in megabytes or gigabytes (or mebibytes or gibibytes) by using suffixes, e.g. 2G, 768M, just like the "capacity" key of the --volume option already allows.
Thanks.
