document (for developers) how to create Qubes Live USB

[mfc]

this will help with potential developers / maintainers testing the Qubes Live USB #1018.

In short: same as installation ISO, but set ISO_LIVEUSB=1 in builder.conf. And optionally ISO_INSTALLER=0 to not build the installation ISO.

Internally all the scripts are in installer-qubes-os component, especially livecd-creator-qubes tool and kickstart file. Status of 3.1 image is that, salt management doesn't work during ISO build, so it can't setup Whonix VMs. The solution for that is using "offline mode" (see current kickstart file) but through Saltstack qvm module. Probably that module (or qvm-tools?) should detect when running in chroot and switch to offline mode automatically.

There is work in progress (mostly abandoned now) branch with partial port to full R3.1 (including Whonix etc):
https://github.com/marmarek/qubes-installer-qubes-os/tree/liveusb-wip

AFAIR it fails during build on out of disk space on the target image. Don't remember exact number, but it was something huge (10G? 20G?)
