What type of PR is this?
/kind cleanup
What this PR does / why we need it:
The use of the generic 'DEBUG' name in varialbes or flags can be very
problematic and lead to difficult to troubleshoot problems. Update CI
VM images to those which no-longer react to the
$DEBUGenv. var. Alsoupdate other repository files which make use of the generic form.
How to verify it
CI testing and manual review of documentation.
