Revert "LPS-41253 Revert"

This reverts commit 64a5a2d3e22b3479dbee43846b25d8deba48c4de.
LPS-41253 Still ensure schema is validate as part of test but do not require qualified xmlns for now for compatibility
LPS-40960 Add method to Log so that log wrappers can set their class name for log4j to use when determining the actual logging class
LPS-40960 Implement it in the log4j logger. Changing FQCN to be a member so that we're on the safe side in case it is possible to have multiple log wrappers at the same time.
LPS-40960 Implement the method in LogWrapper and call it from SanitizerLogWrapper so that we don't log line numbers belonging to SanitizerLogWrapper instead of the actual class that's producing the log.
