Investigate whether it's possible to run Spine Logging in scope of apps built with Spine 1.x

[armiol]

In production, many applications use Spine 1.x. However, they may benefit from using this logging library.

All of them run in environments with Java 11 or higher. So theoretically, there should be no issues with including Spine Logging as a dependency.

In scope of this task, one needs to do the following:

1. Try running an application built with Spine 1.x, Java 11+ and Spine Logging.
2. Record any problems.
3. See, how Spine Logging may be improved to fit cloud-based logging systems.
