Immediately render the Value Stream Dashboard data as it is loaded

What does this MR do and why?

Instead of waiting for all the data to finish loading before rendering it in the table, insert the table data as soon as the correlating request finishes.

Also only request metrics that were not excluded from the table. Previously all metrics were requested even when excluded.
