[deploy-it] temp override for deploy branch rules

for ei-prod only.  I set up the ei EB env as prod level, but
have been working on launch changed in master branch. Easy enough to undo,
but I didn't wan't to mess with prod branch until done because
the launch scripts affect all the n1cloud-related environments.
