Description

ContainerLogAppender and ContainerRollingLogAppender both have quite similar functionality as RollingFileAppender. Maintenance of custom appenders for Log4J2 is costly when there is very minor difference in comparison with built-in appender provided by Log4J.

The goal of this sub-task is to replace both ContainerLogAppender and ContainerRollingLogAppender custom appenders with RollingFileAppender without changing any system properties already being used to determine file name, file size, backup index, pattern layout properties etc.
