Zack Cornelius cbc28f0d15 Implement file backed memory for instances in libvirt
File backed memory is enabled per Nova compute host. When enabled, host
will report 'file_backed_memory_capacity' for available memory.

When enabled, instances will create memory backing files in the
directory specified in libvirt's qemu.conf file 'memory_backing_dir'
config option.

This feature is not compatible with memory overcommit, and requires
'ram_allocation_ratio' to be set to 1.0
