Jean-Paul Calderone 66903ba3d7 Make the environment a mapping
The documentation explains it as a list of single mappings.  That makes
no sense but "no sense" is par for the course.  However, "circleci
config validate" is happy if it is merely a mapping.

Making it a mapping lets us do a yaml mapping merge later and reduce
duplication.
