Zero config support akin to `exo`

[0x7CFE]

Hi! First of all thank you for the amazing project!

IIUC, Сake requires everything to be set up beforehand, i.e. define nodes, split models and assign addresses.

I am wondering if it's at least theoretically possible to add zero config layer that would do this work automagically? Something very similar already exists in Exo, But... Python... 🤦

Also, the ability to have dynamic cluster is very appealing.
