Hi all,

This review takes into account the previous review recommendations:
        - change args.get with default values
        - change list() so that it returns
                - default the environment file related to the instance
                  (/etc/sysconfig/dirsrv-<serverid> or $HOME/.dirsrv/dirsrv-<serverid>)
                - all the environment files if called with 'list(all=True)'
        - change exists() to return 'len(self.list()) == 1'
        - start() rebinds to the instance so that its final state is DIRSRV_STATE_ONLINE
        - List( ) returns a list of dictionaries. Each dictionary is built from config files found under <prefix>/etc/sysconfig/dirsrv-* or $HOME/.dirsrv/dirsrv-*. The dictionary contains a kind of <propname>:<value> where propname are basically the environment variable set in those file. By default, list () only returns its instance config file (if it exists). Else it returns all the instances.
        - minor changes to set the 'sroot' attribute from what is found in SERVER_DIR of the config file
