The referenced Munin plugins have been updated to use the Python driver: https://github.com/comerford/mongo-munin.

The REST API is not required (nor should it be enabled as per our security best practices) so we should remove mention of this.

fwiw, there some other contributed Munin plugins also using the Python driver: if we want to mention for completeness: http://munin-monitoring.org/browser/munin-contrib/plugins/mongodb/.
