This conversation was spawned from the n + 1 problem we're experiencing on #310 (closed). We need a method to batch up the meta-data requests and this method, along with BlobService::GetBlobsByOid (#425 (closed)) will solve the issue.

Once the ~"Client Preparation" work for these two new issues have been solved the TreeEntries route can be re-enabled, since the Rugged versions of the batch interfaces will prevent the additional calls being fired over to Gitaly.
