Bigtable.insert isn't promisified?

Looks like we don't have the promisified verison of insert which is a bummer because the code ends up looking like...

bigtable.getInstances().then(function(data) {
  var instance = data[0][0];
  var table = instance.table(...);
  table.insert(entries, function(err, insertErrors) {
    ...
  });
});

Mixing the promise version and callbacks makes me feel :(
