eliminate guest/guest default username/password and use an explicit sasl mechanism list

      Currently, we default to using the system-default sasl mechanisms list. That
      list will include GSSAPI if the package is installed on the user's system. But
      merely installing the GSSAPI package does not prepare qpidd to use GSSAPI. The
      user must perform specific config steps to make it work. And, since GSSAPI
      will be selected before other mechanisms, this means that many users will see
      qpidd fail as soon as they try --auth=yes .

      It also seems dangerous to allow PLAIN, since users who install qpidd will then
      have an insecure system by default.

      By accepting the system-default list we are allowing too many user-surprises.

      The solution is to explicitly control the mech list, probably only allowing a
      single mechanism such as DIGEST-MD5, and give the user sufficient instruction
      on how to set up other mechanisms when they are desired.

      NOTE – I am also allowing ANONYMOUS, because some python tools do not yet know how to send credentials, and this will allow them to continue working.
