Title: Batch requests should use OData batch end-points instead of JSON-RPC

Switching to OData batch also allows to emit response events.

client.newBatchRequest()
.add(client.plus.people.get({ userId: '' })
.add(client.urlshortener.list())
.add(/* Request object */)
.on('response', function(err, result, index) { ... }) // optional
.withAuthClient(authClient) // optional
.withOpts({}) // optional
.execute(function(err, results) {

});
