[data grid] Implement preloading with server-side data source

[arminmeh]

To improve user experience, we should add a preloading feature to the data source.

It could be made in two iterations:

1. Static config
   I know what is the most demanded state of the grid, so I am asking the grid to fetch and cache that data after initial load (people often sort by name)

2. Prediction
   User is hovering over the name column header. Clicking on it would require sorted dataset. Fetch the data with the future sorting model
