Cube.js not waiting for response from Elasticsearch

**Describe the bug**
While trying to call elasticsearch to get the data into cube.js. It usually takes 5 to 10 seconds to get the response as the volume of data is huge (~ 120 million), but cube.js is not waiting until it gets the response. Also, we could see that the elasticsearch SQL query is still running in the cube.js console and we can get the response into the cube.js the second time as it's already fetched and stored in cube.js cache.

**Expected behavior**
Cube.js must wait until it gets the response from elasticsearch or an option to override the default wait timeout before pushing to cube.js cache.
