Fix for update workflow

Browse Source 
When terminating a function and replacing it during an update,
there was often an error about task precondition not met
which meant having to try and or wait or being left in an
inconsistent state.

The new flow makes sure "Wait" is called in either code path
and allows for a custom gap between the SIGTERM and SIGKILL
through the grace_period env var - set as a Go duration.
