Unable to turn off logging for a particular package

[shanman190]

When configuring logging using Spring Boot's LoggingApplicationListener and SnakeYAML, you're not able to turn off logging for a specific package. This is because of how SnakeYAML handles the word 'OFF' and represents that value as a boolean instead.

My suggestion would be to add some code to the LoggingApplicationListener around setting the LogLevel to check if the level comes in as a String with the value of false and act as if it means 'OFF'

For the record, we did something similar in #2737

...and so the same workaround applies (you need to quote the value).

Summary of the change in #2737: we could allow "false" as a synonym for "OFF".
