config import/export per cli

[Xyz00777]

Is your feature request related to a problem? Please describe.
I would really like to do the system config import/export per cli and not only per webui

Describe the solution you'd like
Please add the commands import and export the configuration per cli and not only by first installation

Describe alternatives you've considered
No

Additional context
It would be really nice to be able to especially export the current system configuration per cli and not only per webui because that would make an automatic backup of the system configuration mutch simpler and automatic. I think based on that it is already implemented for the webui the same backend can be used for the implementation so it should be easy to be implemented.

If it is already implemented, than please document it ;) because at the moment its no implemented here:
