Title: Add support for formatted messages to HealthChecks

This adds convenience methods to automatically format `HealthCheck` messages using `String.format(format, args)`:

For healthy `HeathCheck`s:
```java
Result.healthy("latency: %d", latency);
```

For unhealthy `HealthCheck`s:
```java
Result.unhealthy("timed out after %dms, connecting to %s:%d",
timeout, host, port);
```
