stop overriding log4j configuration

The log4j configuration template provided by this ansible role doesn't reflect current log4j configuration in elasticsearch 6.x and 7.x.
Also this template doesn't contain any variable so everything is hardcoded inside.
As we don't need to override any value inside, let's use standard elasticsearch log4j configuration file provided by elasticsearch package and stop overriding it with this role.
