ci: Initial Windows image integration

This enables the Windows test module. One basic test is enabled,
while all others are disabled yet for aarch64. Jenkins file is
extended with the corresponding step for aarch64.

installAzureCli() is parametrized.

It seems that transferring a 30GB image would take >= 15 minutes. An
optimization here is having a gzip'ed image to 10GB which would unpack
in 3 minutes. Expect to be quicker than transferring an uncompressed
image while on another network.
