This ensures that the index version (aka the "v" field) is always present in the oplog entry when creating indexes on a 3.4 primary. We can therefore assume that if the "v" field isn't present in the corresponding oplog entry, then a v=1 index should be built. Changes MultiBlockIndex::init() to return the index specifications that were actually created. The "repairDatabase", "compact", "copydb", and "cloneCollection" commands no longer automatically upgrade the index version to the current default version. Instead, the only command that does so is the "reIndex" command.
