WFLY-3613 adding a new expose-all-logs parameter to the log-store probe ...

...operation

https://issues.jboss.org/browse/WFLY-3613
This should simply be

final boolean exposeAllLogs = LogStoreDefinition.EXPOSE_ALL_LOGS.resolveModelAttribute(context, operation).asBoolean();

The presence of the default value on EXPOSE_ALL_LOGS means you'll get it if the operation doesn't have the param.
