ag-grid enterprise

[tzachshabtay]

We currently use the open source ag-grid community version.
The enterprise version has more features which we can benefit from (enum filters, column selectionn, groupings and aggregations, and the ability to expand a row so we can show the json view inside the grid).

Need to check if ag-grid has a license which allows open source projects to use the enterprise edition. Otherwise, perhaps we can add it as a feature flag (the user will need to enter their ag-grid license key which will unlock the extra features).
