This adds arm64 ubuntu-minimal Jammy functests and x86 ubuntu image
based Jammy functests. To make this happen we have to install
debootstrap from debian unstable on the functest nodes in order to get
access to a debootstrap that knows what jammy is.
As we ramp up Jammy support in our tools having good testing will be
helpful.
