Creates a policy that resets once the component has operated without failing
for the given duration. Repeated healthy reports do not move the starting
point; only a failure clears it.
Parameters
healthyForMs: number
How long the component must operate without failing,
in milliseconds; must be a positive, finite number.
Optionalclock: ()=>number
The time source used to measure the healthy stretch; defaults
to a monotonic clock. Primarily for testing.
