    Move some libvirt specific flags into a group

    This is backwards compatible via deprecated groups. This change
    moves the flags defined in nova/virt/libvirt/driver.py into a
    "libvirt" configuration group.

    There are other flags which need to be moved, but this change
    is quite large, so I will handle those in follow up changes.

    Now that the flags in nova/virt/libvirt/driver.py are in a libvirt
    group, we can drop the libvirt_ from in front of many of the flag
    names as well.

    Progresses blueprint libvirt-opts-group.

    DocImpact: the following flags are moved into a "libvirt" flag
    group: rescue_image_id, rescue_kernel_id, rescue_ramdisk_id,
    libvirt_type, libvirt_uri, libvirt_inject_password,
    libvirt_inject_key, libvirt_inject_partition, use_usb_tablet,
    live_migration_uri, live_migration_flag, block_migration_flag,
    live_migration_bandwidth, snapshot_image_format,
    libvirt_vif_driver, libvirt_volume_drivers

    The following flags have had the libvirt_ dropped from the start of
    their flag name now that they are in a flag group:
        libvirt_type (now virt_type)
        libvirt_uri (now conn_uri)
        libvirt_inject_password
        libvirt_inject_key
        libvirt_inject_partition
        libvirt_vif_driver
        libvirt_volume_drivers
        libvirt_disk_prefix
        libvirt_wait_soft_reboot_seconds
        libvirt_non_blocking
        libvirt_cpu_mode
        libvirt_cpu_model
        libvirt_snapshots_directory

    The name for the virt_type flag was influenced by bug 1195361,
    which shows confusion as to what the flag is setting (the
    virtualization type libvirt uses, not the driver libvirt uses
    to achieve that).

    Finally, the flag libvirt.nonblocking has been renamed to
    libvirt.api_thread_pool, which is more descriptive.

The automatic docs were picked up, but looks like there are still mentions in the config ref still using the old terms.
