To execute a slapconsole script, we could only do:

`slapos console < script.py`

Extend this API so that we can simply use

`slapos console script.py`

inspired by `python script.py`

Include a panel shortcut panel, which is usefull for include per master shortcuts to expose to links for quick request for example.

include n.me is mandatory.

Current design don't allow us to know the precise status of a slave, part of another software instance.
