Upgrade log4j2 to 2.17.2

Log4j 2.17.2 has been released to:

• Over 50 improvements and fixes to the Log4j 1.x support. Continued testing has shown it is a suitable replacement for Log4j 1.x in most cases.
• Scripting now requires a system property be specified naming the languages the user wishes to allow. The scripting engine will not load if the property isn't set.
• By default, the only remote protocol allowed for loading configuration files is HTTPS. Users can specify a system property to allow others or prevent remote loading entirely.
• Variable resolution has been modified so that only properties defined as properties in the configuration file can be recursive. All other Lookups are now non-recursive. This addresses issues users were having resolving lookups specified in property definitions for use in the RoutingAppender and RollingFileAppender due to restrictions put in place in 2.17.1.
• Many other fixes and improvements.
