Check-style issue is due to more number of parameters.

> We introduce a way to limit the number of opportunistic containers that will be allocated
on each AM heartbeat.
>  This way we can restrict the number of opportunistic containers handed out by the system,
as well as throttle down misbehaving AMs (asking for too many opportunistic containers).
