Restoring the ability to run fake mode locally.

* Adding a fix which makes it easy to change logging. This is useful
  if you want to write a script to start a server, run some tests,
  and stop it.
* Fixed the configuration files which were preventing some stuff
  from working when the fake mode process started. Had to create a
  test api-paste.ini file to use the fake keystone auth.

Fixed bug #1122526
