This strategy defines health checks which, before v3.6.0, were run by the /health endpoint.
Since v3.6.0 the strategies configured in systemOptions.healthChecks are not executed, and this
interface will be removed in v4.0.0. See the health checks guide.
The example below shows how strategies were configured before v3.6.0.
Example
InjectableStrategy() => HealthIndicatorFunctionShould return a HealthIndicatorFunction which performs the check and resolves to a status payload. Since v3.6.0 this method is never called.
