Infrastructure for config database upgrade (adding epochs in v4)

      In order to support SERVER-939's distribution/moving of unsharded collections, we need to add epochs to all collections and chunks in the config server without them.

      v2.2 mongos and mongod processes are capable of handling epochs, and will preserve them, but collections which existed in 2.0 clusters may not.
