What this PR does / why we need it:
This PR fixes webhook requests getting routed to starting and stopping gatekeeper pods, that are not ready to serve requests. The implications of this behaviour are explained in #3776

Fixes #3776
Special notes for your reviewer:
The grace period for handling termination will not work when using Tilt to test. It will terminate instantly, like it did before.
We tracked this down to the rerun-process-handler Tilt uses to wrap the application to test.
The start.sh script traps SIGTERM and INTERRUPTS, the two signals we handle, and replaces them with SIGKILL, which we do not intercept.
