------------------------


start_parallel_sdmadm_command currently needs a list of hosts where the
command should be started parallel.

It would be nice if the command could also be started parallel on the same host
(in an additional shells) or only on a view hosts.

The parameter host_list should not be needed for finding out the task_infos
which have to be defined for setting up the commands.

So main task is to make the parameters host_list and task_info independent
