** To remove ** Update logging dependencies
Added tests for custom handlers and log4j appenders as a custom handler.
[AS7-6296] Removed the logmanager configuration implementations. Updated log4j appenders to use POJO configuration.
[AS7-6307] Use new ContextSelector and register the logging API class loaders in the context loader. Prevents loggers from get created on the incorrect log context.
[AS7-5255] Create a strong reference log context for log4j configurations.
