[ALS-5053] pen test medium stacktrace error (#85)

* [ALS-5000] Update maven compiler plugin
Maven compiler plugin has a dependency on log4j.

* [ALS-5053] Add error pages to web.xml
* [ALS-5053] Add value to server.xml
This value will intercept request processed by tomcat. I have disabled reports and show server information. This information should not be returned to the client.
