Bug 1365828 - mongo log spam

[John Meinel]

I don't think these are from authentication between mongo instances.
This looks more like a Mongo 2.4 vs 2.6 difference. We added stuff like
"clusterAdmin" to priviledges that we give because of 2.6 support (I
thought).. But if 2.4 doesn't know anything about "clusterAdmin" then
whenever we log in, it goes through the list of roles and noisily ignores
some of them.

Presumably the real fix is to only give roles that are 2.6 specific when we
know we're running against 2.6 ?

(I could be wrong on this, but I thought we had earlier bugs that we
couldn't do the cluster reconfiguration on 2.6 because we had to add the
"clusterAdmin" role.)
