Ticket 47625 - CI lib389: DirSrv not conform to the design
    
    Bug Description:
    	Changes to make DirSrv class conform to the design  http://port389.org/wiki/Upstream_test_framework
    
    Fix Description:
    	The fix introduces several changes
    		- Define SERVER properties with "verb" that could be used in CLI
                      Those properties are used in 'args' dictionary to handle the instance (create/delete...)
    		- Split the previous lib389.DirSrv:__init__, __localinit__ and __initPart2 into
                      __init__/allocate/create/open
    		- Implements lib389.DirSrv:delete/close/start/stop/restart/list/exists
    		- Copy tools functions related to instance backup into instance class lib389.DirSrv
    			clearBackupFS/checkBackupFS/backupFS/restoreFS
    		- Add a new test module for DirSrv: dirsrv_test.py
    		- List returns the properties retrieve from the config files
                      (<prefix>/etc/sysconfig/dirsrv-* or $HOME/.dirsrv/dirsrv-*
