* clone_system client

The UI is limited and weird (at best):

```
yast2 clone_system modules clone=software,partitioning
```

The generated profile is usually bigger than it should be. Additionally, what
if you want to use a different file than `/root/autoinst.xml`?

* autoyast client

It does not work well at this point:

```
    # yast2 autoyast modname=bootloader
    Unknown Command: modname=bootloader
    Use 'yast2 autoyast2 help' for a complete list of available commands.
    # yast2 autoyast2 help
    No such client module autoyast2
    # yast2 autoyast module modname=bootloader
    ## -> open yast UI and start given module
    # yast2 autoyast file filename=/root/autoinst.xml
    ## -> open yast UI and load given xml
    # yast2 autoyast file filename=/root/autoinst.xml module modname=bootloader
    Unknown option for command 'file': modname
```
