Ticket 48951 - dsadm dsconfig status and plugin
    
    Fix Description:  Add support for dsadm and dsconf to be able to check the
    server status. Additionally, we add plugin support, and move fixtures to a
    shared fixture module.
    
    For example:
    
    > dsadm instance status
    Directory Server instance name : localhost
    INFO:dsadm:Instance is running
    
    > dsconf -D 'cn=Directory Manager' -H ldap://localhost plugin list
    Enter password for cn=Directory Manager on ldap://localhost :
    
    INFO:dsconf.plugin_list:7-bit check
    INFO:dsconf.plugin_list:Account Policy Plugin
    INFO:dsconf.plugin_list:Account Usability Plugin
    ...
    INFO:dsconf.plugin_list:SSHA384
    INFO:dsconf.plugin_list:SSHA512
