    @tillrohrmann Could you please help to review this pr? And there is a question, the pending requests in slot managers are not in order. So requests arrived later may be fulfilled earlier, does this matter?

> In flip6, for yarn mode, it request containers from yarn according to the resource profile in slot requests. And when slots come back after container starting up, we should supporting an optimal matching based slot manager which can assign the slot to the request whose resource profile closest to it. This could reduce resource waste and avoid OOM.
