Issue JSW-5268: Perform work modes initial XHR calls in parallel
At the moment we perform three XHR calls in order to render a rapid board in series: First we get the rapid board selector data. Then we get the rapid board config data. Finally we get the issues data (allData). For the 99% case we should be able to perform all three of these calls in parallel (kick them all off at the same time), and just perform the rendering in series. This will kill off the Rapid Board selection drop down This means we will have to perform an additional two rest calls in the unlikely case where someone attempts to load a rapid board that has been deleted and gets punted to the default board.
