environment
FOOwith no value nor equal sign means "propagate value from user's environment, or unset variable"So, as we resolve environment, empty value with no matching entry in user's environment MUST not result into removing entry from service definition.
Build args do not follow this rule.
--build-arg FOOwill propagate user's environment value, but if not set build arg will keep using value set by Dockerfilefixes docker/compose#11962
supersede #634
