Previously, MongoDB 2.4 (from juju-mongodb) and the system installed
MongoDB (2.6) were preferred over MongoDB 3.2 (which is actually used
in production).
Cache the MongoDB path alongside the version. Previously there was a
small chance that the cached version would not match the mongod
version. This also avoids unnecessarily looking up the mongod path all
the time.
