Session Timeout needs to be converted to minutes for Tomcat

PLEASE NOTE: Tomcat uses MINUTES for the session-timeout property.
The first commit is false because it changes the interface AbstractConfigurableEmbeddedServletContainer, and the change from seconds to minutes is now in the tomcat factory.
Fixed tests that used the tomcat factory

EDIT: Sorry, I forgot to put a BUG label on this issue.
EDIT2: I am not sure about this but it should be checked. If sessionTimeout is not set than it is maybe set to 0 or -1 what than means that sessions don't expire. That was the reason I investigated session timeouts.
