[Pki-devel] [PATCH] 287 Refactored CLI framework.

A new SubsystemCLI class was added as the base for subsystem CLI modules. The MainCLI was modified such that it will only perform authentication if the subsystem is specified in the server URI. If no subsystem is specified in the URI, the authentication will be done by the subsystem CLI module. Ticket #701 -- Endi S. Dewata
