    Bug Description: Move DS Admin Code into Admin Server - admin server setup
    Reviewed by: nhosoi (Thanks!)
    Fix Description: This implements support for admin server configuration and reconfiguration, so that we can remove setuputil related code from admserv/newinst/src.  The basic flow is this:
    Ask user basic information.
    Ask user if they want to either use an existing config ds or setup a new one.  If the user selects No, the code will gather information, create the directory server, and set it up to be the configuration DS.  Otherwise, it will just create the directory server and register it with the existing config DS.  The code will also create and setup and start the admin server, or reconfigure it and restart it as needed.  Note that setup-ds-admin.pl assumes that a config DS is to be used.  If you want to setup a directory server instance without using a config ds, use setup-ds.pl instead.
    Platforms tested: RHEL4
