Traffic Router not logging at INFO level across all modules

[elsloo]

With the current configuration the default logging level is WARN except for the core module/package. Specifically, modify the following log4j.properties such that we have INFO log levels across all modules/packages in Traffic Router. This is required for visibility for operations – currently we're unable to tell whether or not we're reloading the Neustar database upon download, and if so when.

# Set root logger level to DEBUG and its only appender to A1.
# Valid levels are: ALL, TRACE, DEBUG, INFO, WARN, ERROR, FATAL, NONE
log4j.rootLogger=WARN, A1

# Set application logger levels
log4j.logger.com.comcast.cdn.traffic_control.traffic_router.core=INFO
