Add Configuration to PatternLayout backport(97679) (#97971)

in 2.17.2 (patch release) log4j has made a refactoring that requires a Configuration to be manually passed into the created PatternLayout
If the Configuration is not passed, the System Variable lookup will not work This results in cluster.name field not being populated in logs

This commit creates a PatternLayout with a DefaultConfiguration (the same was used previous to the refactoring)

backports #97679
