Tool slptool used in model/peer.py but missed providing it as a dependecy

I see that slptool is called in model/peer.py file but no where the package provides this tool mentioned as dependency.

I guess this has to be reflected in spec, dependency packages list and documentation wherever necessary.

The federation feature is optional, ie, the user needs to enable it manually to get it.
IMO it should not be a required package but we can list it as suggested - at least for the DEB package.
But I am not sure the spec file has the similar parameter.
