The default logging format in the runtime pod uses time in format "hours since pod started"). This is bad way for indexing it into Splunk. Thus we need to change it to look like in the good old days of VM:

formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%d{yyyy-MM-dd HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%e%n
