- Allow the use of system provided certificate setup that may be incorporated
  into the SSL library used on the specific system
  + At present we either use the default certificate bundle we ship with the
    boto source, or we force a user/integrator to create a bundle file of their
    own. Linux distributors build the way certificates are used and validated

    way of certificate handling by setting the configuration to the new
    "system" keyword.
