Fix MachinePool poll interval for sharded controller

[2uasimojo]

Previous work (#2310 / 4117577) added a knob to control the poll interval for the MachinePool controller.

Then a subsequent effort (#2341 / 35ce9c6) split the MachinePool controller into its own StatefulSet.

But the latter forgot to carry the poll interval plumbing into the sharded version of the controller.

Fix.
