HealthService fix TODO

[tjquinno]

I assume this is the TODO you mean to refer to:

helidon/nima/observe/health/src/main/java/io/helidon/nima/observe/health/HealthFeature.java

Lines 149 to 159 in 652c517

	@Override
	public HealthFeature build() {
	providers.build()
	.asList()
	.stream()
	// TODO use configuration
	.map(provider -> provider.healthChecks(Config.empty()))
	.flatMap(Collection::stream)
	.forEach(it -> addCheck(it, it.type()));
	return new HealthFeature(this);
	}
