[logback-user] Log Message regardless of Log Level

[Shane Kelly]

Hi Daniel,

Thanks for the info - glad there are others out there with similar
requirements. I guess a separate logger specifically for this purpose is
another way to approach it alright - definitely worth considering. I think
I'm gonna try extending the existing ThresholdFilter (or creating a new
filter based on it) as a first attempt, see how that goes, and failing that
try the separate logger route. Good to have options.

Regards,

Shane
