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 Change-Id: I676291ec0faa1dea0bd5050ef8e3426d171de4c6 Implements: blueprint libvirt-file-backed-memory
