feat: introduce topos-node crate

[Freyskeyd]

Description

This PR introduces a dedicated crate for the topos runtime, decoupled from the topos CLI that can be used by node operator.
The purpose of the topos-node crate is to have everything to run a node from a config file.

This PR is just moving things around and the topos CLI should keep working as expected.
The topos node up command is going to be deprecated, the replacement being the topos-node binary.

It would be good to have a sibling PR for the topos-playground as a sort of test that everything works as expected after this lands.

[Freyskeyd]

This PR is backward compatible with the current CLI command. I think you mean updating the local-erc20 right?

I think you mean updating the local-erc20 right?

Yeah, I think that's what I meant! :)

I was thinking about how the topos-playground exercises the whole stack, but you're right, it's the local-erc20 image that is relevant here.
