Change default logging setting to non-verbose

[Arkatufus]

Fix #191

[Aaronontheweb]

@Arkatufus I think we need to change the loglevels on these calls to Debug, is more what I meant - even with this setting on.

Need to address the PersistenceLivenessProbe too

akkadotnet-healthcheck/src/Akka.HealthCheck.Persistence/AkkaPersistenceLivenessProbe.cs

Line 151 in b5189a9

_log.Info("Received recovery status {0} from probe.", livenessStatus);

- that's the biggest offender at the moment

[Aaronontheweb]

There are multiple callsites in the persistence liveness probe that need to be updated - I just grabbed one example.
