IMPALA-4822: Dynamic log level changes to Catalog and Frontend JVMs

Very often we have to change the log4j logging levels
of Impalads and Catalog server for debugging purposes.
Currently, there is no way to do that without a restart
of the daemons, which is not a viable option in production
deployments.

This patch addresses this supportability gap by exposing
the ability to set dynamic log4j logging levels using
a simple web endpoint on Impalad and Catalog web pages.
