Firmware installation

Cloud-init has no firmware in it, so i915 driver is needed to install.

When the app node is initiated by ansible, firmware-intel-graphics and intel-media-va-driver-non-free are installed. And only when they are installed, update-initramfs -u and reboot modules run as a handler.

Verification

After reboot, check the render device.

ls -l /dev/dri
# crw-rw---- 1 root video 226,   0 ... card0
# crw-rw---- 1 root render 226, 128 ... renderD128
