Add an overlay for local development on Tilt (#1773)

Adds an overlay that removes the liveness and readiness probes
as well as the --leader-elect flag from the operator-controller-controller-manager deployment since those will cause container restarts when the go debugger is stopped at breakpoints. Also edits the Tiltfile to use this new overlay target.

Also adds our 1 existing feature flag to the new overlay.
