Added HBAC Test page.

This is the initial implementation of HBAC Test page. Currently it
can select user, source/target group, service, rules, and execute
the test. Other functionalities to be implemented include the search
filter, external users/hosts, back/next buttons, validation, styling,
and internalization.
