[RFE]: Better handling of large instackenv.json files

[Udi Kalifon]

I generated a large instackenv.json file (of 500 nodes) and tried to import it with the GUI. On the browser's console you can see the file processed node-by-node, but if the user doesn't have the console open it freezes the browser and you can't click on anything and can't open the console to see what's going on.

We need to:
1) Display a progress bar while the file is processed.
2) Limit the number of nodes the file can include, to what we can process in a reasonable time. The 500 nodes I'm trying to import are already taking more than 10 minutes.
3) If possible, improve the performance to be able to support even larger imports.

Also, once the list does finally show up on the dialog, if you want to select one of the nodes from the list you have to scroll the whole dialog down - and then you can't see the node details any more. We should allow seeing the selected node in the list, even it's a long list, and seeing the node details at the same time.

@Udi - What do you think about adding a progress bar between uploading the JSON file and showing the list of nodes in the register modal? Also, I've added a scroll bar in the design in the case that there are a large number of nodes. I made sure to note that this should only scroll in the left panel so that the user will always be able to see the node detais on the right:

Hi Liz. The progress bar and the scroll bar look very nice. We need to implement something along these lines. Thanks !

The GUI is no longer developed, do we want to close this bug?

[Udi Kalifon (ukalifon)]

Closing the bug because the GUI is no longer maintained.
