Making certfile/keyfile optional, so that vnc_api can rely on CA or CA/CERT.

Change-Id: Iffb9bf9d8cf23fe3943335565bf2adaf878c5df8
Partial-Bug: 1630513
(cherry picked from commit d7407a1fbb0876f0a84a0864824b3eb3c6ef591d)

Issue:
Password is displayed in the log files of the config daemon, during
uncaught exceptions.

Fix:
cgitb sets sys.excepthook to format uncaught exceptions. Deriving the
cgitb Hook and modifying the handle method to mask password along
with formatting.
