Set termination grace period upon function updates

This was missed from openfaas#869 and fixes the controller so that
it updates the termination grace period for functions.

The problem would be that if a user updated the
write_timeout variable used to compute the grace
period, it would be ignored.

The operator uses common code for deploy/update, so does
not need a separate change.

Thanks to @kevin-lindsay-1 for doing exploratory testing
to find this.

Add 2s jitter to termination grace period

The additional 2s should prevent an issue where the grace
period is exactly the same as the timeout, and kills the Pod
before the remaining requests have completed.
