Since tuskar-ui now uses the FormsetStep for the flavors in the resource class create/edit dialog, a lot of the custom DataTable code is no longer needed, so I removed it. There is still a custom Row class needed for pre-selecting the checkboxes in the Racks table in the resource class create/edit. Change-Id: I51647309ddccafba1d8e07ad12586e6bf2d1badd
