Update sample cdr_tds configuration to try and eliminate some confusion.

Also change the preferred configuration option from 'hostname' (which was
misleading because it didn't actually treat the value as a hostname) to
'connection' and added some verbage explaining that the user would need to
refer to their freetds.conf file for those settings.  'hostname' was kept
as a backwards compatible configuration parameter.
